FormatFloat('0.00',qrysth.Fields[i].AsFloat) 将给出“12.00”。

为了能够得到“12.000000000000000”,您应该自己进行舍入,因为不会损失精度。

FormatFloat('0.00',qrysth.Fields[i].AsFloat) will give '12.00'.

To be able to get '12.000000000000000' you should do the rounding yourself, as there's no loss of precision.

这是单个标签的解决方案

function subStrWithoutBreakingTags(str, start, length) {
    var countTags = 0;
    var returnString = "";
    var writeLetters = 0;
    while (!((writeLetters >= length) && (countTags == 0))) {
        var letter = str.charAt(start + writeLetters);
        if (letter == "<") {
            countTags++;
        }
        if (letter == ">") {
            countTags--;
        }
        returnString += letter;
        writeLetters++;
    }
    return returnString;
}

it is solution for single tags

function subStrWithoutBreakingTags(str, start, length) {
    var countTags = 0;
    var returnString = "";
    var writeLetters = 0;
    while (!((writeLetters >= length) && (countTags == 0))) {
        var letter = str.charAt(start + writeLetters);
        if (letter == "<") {
            countTags++;
        }
        if (letter == ">") {
            countTags--;
        }
        returnString += letter;
        writeLetters++;
    }
    return returnString;
}

在您调用的服务方法中,将这 4 行代码插入到下面函数的开头。

    public string GetEmployee(string id, string name, string email)
    {
        WebOperationContext.Current.OutgoingResponse.Headers.Add(
            "Access-Control-Allow-Origin", "*"); WebOperationContext.Current.OutgoingResponse.Headers.Add(
            "Access-Control-Allow-Methods", "GET"); WebOperationContext.Current.OutgoingResponse.Headers.Add(
            "Access-Control-Allow-Headers", "Content-Type, Accept");
        Employee employee = new Employee();
        employee.TRGEmpID = id;
        employee.First_Name = name;
        employee.Email = email;
        EmployeeManagement empMgmt = new EmployeeManagement();
        var json = new JavaScriptSerializer().Serialize(empMgmt.Search(employee).FirstOrDefault());
        return json;
    }

另外,在 svc 文件中,在函数之前添加这一行,如下所示。

        [OperationContract]
    [WebInvoke(Method = "GET",
       ResponseFormat = WebMessageFormat.Json,
       RequestFormat = WebMessageFormat.Json,
       BodyStyle = WebMessageBodyStyle.Bare)]
    string GetEmployees(string name);

如果你也需要 web.config,这里是

<?xml version="1.0"?>

<system.web>
    <compilation debug="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>
    <services>
        <service  name="EmployeeService.EmployeeSearchService" behaviorConfiguration="DefaultServiceBehavior">
            <endpoint binding="webHttpBinding" contract="EmployeeService.IEmployeeSearchService"      behaviorConfiguration="DefaultEPBehavior" />
        </service>
    </services>
    <behaviors>
        <endpointBehaviors>
            <behavior name="DefaultEPBehavior">
                <webHttp />
            </behavior>
        </endpointBehaviors>
        <serviceBehaviors>
            <behavior name="DefaultServiceBehavior">
                <serviceMetadata httpGetEnabled="true" />
                <serviceDebug includeExceptionDetailInFaults="true" />
            </behavior>
        </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
<system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
    <!--
    To browse web app root directory during debugging, set the value below to true.
    Set to false before deployment to avoid disclosing web app folder information.
  -->
    <directoryBrowse enabled="true"/>
</system.webServer>

in your service method you are calling, insert these 4 lines of code in start of the function below.

    public string GetEmployee(string id, string name, string email)
    {
        WebOperationContext.Current.OutgoingResponse.Headers.Add(
            "Access-Control-Allow-Origin", "*"); WebOperationContext.Current.OutgoingResponse.Headers.Add(
            "Access-Control-Allow-Methods", "GET"); WebOperationContext.Current.OutgoingResponse.Headers.Add(
            "Access-Control-Allow-Headers", "Content-Type, Accept");
        Employee employee = new Employee();
        employee.TRGEmpID = id;
        employee.First_Name = name;
        employee.Email = email;
        EmployeeManagement empMgmt = new EmployeeManagement();
        var json = new JavaScriptSerializer().Serialize(empMgmt.Search(employee).FirstOrDefault());
        return json;
    }

also, in svc file add this line before your function like in the one below.

        [OperationContract]
    [WebInvoke(Method = "GET",
       ResponseFormat = WebMessageFormat.Json,
       RequestFormat = WebMessageFormat.Json,
       BodyStyle = WebMessageBodyStyle.Bare)]
    string GetEmployees(string name);

if you need web.config too, here it is

<?xml version="1.0"?>

<system.web>
    <compilation debug="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>
    <services>
        <service  name="EmployeeService.EmployeeSearchService" behaviorConfiguration="DefaultServiceBehavior">
            <endpoint binding="webHttpBinding" contract="EmployeeService.IEmployeeSearchService"      behaviorConfiguration="DefaultEPBehavior" />
        </service>
    </services>
    <behaviors>
        <endpointBehaviors>
            <behavior name="DefaultEPBehavior">
                <webHttp />
            </behavior>
        </endpointBehaviors>
        <serviceBehaviors>
            <behavior name="DefaultServiceBehavior">
                <serviceMetadata httpGetEnabled="true" />
                <serviceDebug includeExceptionDetailInFaults="true" />
            </behavior>
        </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
<system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
    <!--

实际上,这不会在脚本超时时运行。
并且最好在代码中处理无限循环的捕获。

actually, this won't run on script timeout.
and it would be better to handle catches for infinite loops in the code.

听起来您想要的是将等价组与对象实例分开。

制作一个 Map>并注意,当您查找一个对象时,该集合将包含其自身。

Sounds like what you want are to separate the equivalence groups from the object instances.

Make a Map<FooBar, Set<FooBar>> and note that when you lookup an object the set will include itself.

使用 .next 代替:

>>> s = '<table border="0" cellspacing="2" width="800"><tr><td colspan="2"><b>Name: </b>Hello world</td></tr><tr>'
>>> soup = BeautifulSoup(s)
>>> hello = soup.find(text='Name: ')
>>> hello.next
u'Hello world'

.next.previous 允许您按照解析器处理文档元素的顺序移动文档元素,而同级方法与解析树一起使用。

Use .next instead:

>>> s = '<table border="0" cellspacing="2" width="800"><tr><td colspan="2"><b>Name: </b>Hello world</td></tr><tr>'
>>> soup = BeautifulSoup(s)
>>> hello = soup.find(text='Name: ')
>>> hello.next
u'Hello world'

.next and .previous lets you move through the document elements in the order they were processed by the parser, while sibling methods work with the parse tree.

设置Return-Path:(退回)地址Return-Path: 地址指定退回通知应发送到的位置,并使用setReturnPath() 设置消息的方法。

您只能有一个返回路径:,并且不得包含个人姓名。

退回通知将发送至以下地址:

$message->setReturnPath('[email protected]');

Setting the Return-Path: (Bounce) Address The Return-Path: address specifies where bounce notifications should be sent and is set with the setReturnPath() method of the message.

You can only have one Return-Path: and it must not include a personal name.

Bounce notifications will be sent to this address:

$message->setReturnPath('[email protected]');

在按钮的配置中,作为处理程序属性的同级,您可以添加一个scope: newWizardWindow 属性吗?我不能 100% 确定这是否有效,但我认为会的。这会将按钮处理程序的范围设置为窗口,并且在处理程序函数内您可以执行 this.hide();

In your configuration for your button, as a sibling to your handler property, can you add a scope: newWizardWindow property? I'm not 100% sure if that will work, but I think it will. This will set the scope of your button handler to be the window, and inside the handler function you can just do this.hide();

如果您使用自己的适配器来填充列表,那么在构建要返回的视图时的 getView() 函数中,您可以调用 setTag() 在您返回的视图上并存储整个“SingleItem”对象。然后,在返回的视图的 onClickListener 中,您可以使用已单击视图的 getTag() 方法检索信息。

编辑:
指定我指的是哪个 onClickListener

If you are using your own adapter to populate the list then in the getView() function when building the view to return you can call setTag() on the view you are returning and store the entire "SingleItem" object. Then in the onClickListener of the views you return you can retrieve your info using the getTag() method of the view that has been clicked.

EDIT:
Specified which onClickListener I am referring to

我认为他们非常顽皮,

如果您在该页面上查看页面源代码,并查看他们完成表单的方式,那么您将看到以下内容:

    <SCRIPT TYPE="text/javascript">
<!--
function Circle_calc(GeoForm)
{
var CircleRadius = GeoForm.Circle_radius.value;
if (CircleRadius >= 0)
   {
   GeoForm.Circle_circumference.value =  2 * Math.PI * CircleRadius ;
   GeoForm.Circle_area.value =  Math.PI * Math.pow(CircleRadius, 2) ;
   }
else
   {
   GeoForm.Circle_circumference.value =  "";
   GeoForm.Circle_area.value =  "";
   }
}
//-->
</SCRIPT>


<P>

<FORM>
<TABLE BORDER CELLPADDING=3>
<TR>
<TD><NOBR>radius: <INPUT NAME="Circle_radius" SIZE=4></NOBR></TD>

<TD><INPUT TYPE=BUTTON OnClick="Circle_calc(this.form);" VALUE="calculate"></TD>
<TD ALIGN=RIGHT BGCOLOR="#AACCFF">
<NOBR>circumference: <INPUT NAME="Circle_circumference" SIZE=9></NOBR><BR>
<NOBR>area: <INPUT NAME="Circle_area" SIZE=9></NOBR></TD>
</TR>
</TABLE>
</FORM>

<P>

正如您所看到的,您现在在上下文中拥有 HTML 代码,您实际上可以看到 HTML 执行的脚本。由于脚本位于 HTML 文件内,因此您不需要在 HTML 文件顶部进行导入(如果这是正确的短语)来告诉它要使用哪个脚本文件。

另外,我强烈建议使用 W3c 学校教程,它们要好得多,可以在这里找到: http://www.w3schools.com/w3c/w3c_html.asp

They have been quite naughty methinks,

If you do a view page source on that page, and look at the way THEY'VE done the form, then you'll see this:

    <SCRIPT TYPE="text/javascript">
<!--
function Circle_calc(GeoForm)
{
var CircleRadius = GeoForm.Circle_radius.value;
if (CircleRadius >= 0)
   {
   GeoForm.Circle_circumference.value =  2 * Math.PI * CircleRadius ;
   GeoForm.Circle_area.value =  Math.PI * Math.pow(CircleRadius, 2) ;
   }
else
   {
   GeoForm.Circle_circumference.value =  "";
   GeoForm.Circle_area.value =  "";
   }
}
//-->
</SCRIPT>


<P>

<FORM>
<TABLE BORDER CELLPADDING=3>
<TR>
<TD><NOBR>radius: <INPUT NAME="Circle_radius" SIZE=4></NOBR></TD>

<TD><INPUT TYPE=BUTTON OnClick="Circle_calc(this.form);" VALUE="calculate"></TD>
<TD ALIGN=RIGHT BGCOLOR="#AACCFF">
<NOBR>circumference: <INPUT NAME="Circle_circumference" SIZE=9></NOBR><BR>
<NOBR>area: <INPUT NAME="Circle_area" SIZE=9></NOBR></TD>
</TR>
</TABLE>
</FORM>

<P>

As you can see, you now have the HTML code in context, and you can actually see the script that the HTML executes. And as the script is inside the HTML file, you wouldn't need to have an import (if that's the right phrase) at the top of your HTML file telling it which script file to use.

Also I would strongly recommend using the W3c Schools tutorials, they're miles better and they can be found here: http://www.w3schools.com/w3c/w3c_html.asp

看起来您只需要清除浮动

您可以通过将 overflow:hidden 添加到 #container(或者可能是 #divBody)来实现此目的。

有关清除浮动的更多信息:

学习如何以及何时清除浮动是 CSS 的重要组成部分。如果你早点掌握它,你会避免很多困惑。

It looks like you simply need to clear your floats.

You can do this by adding overflow: hidden to #container (or perhaps #divBody).

Some further information about clearing floats:

Learning how and when to clear floats is an important part of CSS. You'll save yourself a lot of confusion if you get to grips with it sooner rather than later.

使用 VBScript,无需检查文件是否存在,只需尝试打开它并使用错误陷阱即可。我对批处理不太熟悉,但我怀疑您可以使用类似的技术。

而不是:

    If objFSO.FileExists(someFileVariable) Then _
Set objTESTfile = objFSO.OpenTextFile(someFileVariable, ForReading, True, TristateFalse)

你会:

On Error Resume Next
Set objTESTfile = objFSO.OpenTextFile(someFileVariable, ForReading, True, TristateFalse)
If Err.Number= 0 Then
    ' opened ok, do stuff
Else
    ' failed, do something else
End If

With VBScript, rather than check to see if the file exists, just try to open it and use an error trap. I'm not as familiar with batch, but I suspect you can use a similar technique.

Instead of:

    If objFSO.FileExists(someFileVariable) Then _
Set objTESTfile = objFSO.OpenTextFile(someFileVariable, ForReading, True, TristateFalse)

You would have:

On Error Resume Next
Set objTESTfile = objFSO.OpenTextFile(someFileVariable, ForReading, True, TristateFalse)
If Err.Number= 0 Then
    ' opened ok, do stuff
Else
    ' failed, do something else
End If
