Repeater .NET 中用户控制器上的自动完成 jQuery
我在 Web 用户控制器上有一个多视图搜索功能,该功能在中继器中调用,天哪!
我在页面上列出了一些培训课程,每个培训课程都调用一个员工搜索 Web 用户控制器,以便人们可以搜索员工以添加到培训课程中。我在页面上的 JS 中列出了员工姓名和员工 ID,并使用 jQuery 自动完成功能让他们搜索员工并填充用户控制器中的隐藏字段。一旦该过程完成,他们可以选择添加另一名员工。
因此,我在所有员工搜索框中都设置了自动完成“工作”,但我执行初始搜索(回发)的自动完成功能将无法再次工作。
然后我将 $().ready(function() 更新为 pageLoad() ,以便它在多个搜索中正常工作,但仅在中继器的最后一项中(jQuery 加载在用户控制器上)
仅供参考:我将 JS 字符串设置为EMPLOYEENAME|ID 和 jQuery 显示员工姓名,如果他们选择它,则会将 ID 放入 ASP:HIDDEN Field
<script type="text/javascript">
format_item = function(item, position, length) {
var str = item.toString().split("|", 2);
return str[0];
}
function pageLoad() {
$("#<%=tb_EmployeeName.ClientID %>").autocomplete(EmployeeList, {
minChars: 0,
width: 500,
matchContains: true,
autoFill: false,
scrollHeight: 300,
scroll: true,
formatItem: format_item,
formatMatch: format_item,
formatResult: format_item
});
$("#<%=tb_EmployeeName.ClientID %>").result(function(event, data, formatted) {
var str = data.toString().split("|", 2);
$("#<%=hf_EmployeeID.ClientID %>").val(str[1]);
});
};
</script>
我已经可以猜测,通过在用户控件中重复 pageLoad,我会覆盖之前的 pageLoad
问题: 有没有办法解决这个问题,让所有 jQuery 出现在单个 pageLoad 中,或者以某种方式让单个 jquery 调用来处理我的所有搜索框,
因为我无法将 jQuery 移动到调用所有控制器的页面中,因为我无法引用特定的 tb_EmployeeName 文本框和 hf_EmployeeID 隐藏字段
非常感谢您为我解决此问题提供的任何帮助或见解。< /strong>
这是用户控制器上的多视图
<asp:MultiView ID="mv_EmployeeArea" runat="server" ActiveViewIndex="0">
<asp:View ID="vw_Search" runat="server">
<asp:Panel ID="eSearch" runat="server">
<b>Signup Employee Search</b> (<i>Last Name, First Name</i>)<br />
<asp:TextBox ID="tb_EmployeeName" class="EmployeeSearch" runat="server"></asp:TextBox>
<asp:HiddenField ID="hf_EmployeeID" runat="server" />
<asp:Button ID="btn_Search" runat="server" Text="Search" />
</asp:Panel>
</asp:View>
<asp:View ID="vw_Confirm" runat="server">
<b>Signup Confirmation</b>
<asp:FormView ID="fv_EmployeeInfo" runat="server">
<ItemTemplate>
<%#(Eval("LastName"))%>, <%#(Eval("FirstName"))%><br />
</ItemTemplate>
</asp:FormView>
<asp:Button ID="btn_Confirm" runat="server" Text="Signup this employee" /> <asp:Button ID="btn_Reset3" runat="server" Text="Reset" />
</asp:View>
<asp:View ID="vw_ThankYou" runat="server">
<b>Thank You</b><br />
The employee has been signed up and an email confirmation has been sent out.<br /><br />
<asp:Button ID="btn_Reset" runat="server" Text="Reset" />
</asp:View>
</asp:MultiView>
------------更新-------------
感谢 Nalum,我能够以比我之前(已删除)尝试更好的方式解决问题。现在我有一个函数可以处理搜索框的所有实例,而无需为创建的每个搜索框生成更多代码。
在包含中继器的父页面上调用以下 javascript。
format_item = function(item, position, length) {
var str = item.toString().split("|", 2);
return str[0];
}
function pageLoad() {
$(".ea_Autocomplete").each(function(i, element) {
var tb_EmployeeName = $(this).children('input[id*=tb_EmployeeName]:first')
var hf_EmployeeID = $(this).children('input[id*=hf_EmployeeID]:first')
tb_EmployeeName.autocomplete(EmployeeList, {
minChars: 0,
width: 500,
matchContains: true,
autoFill: false,
scrollHeight: 300,
scroll: true,
formatItem: format_item,
formatMatch: format_item,
formatResult: format_item
});
tb_EmployeeName.result(function(event, data, formatted) {
var str = data.toString().split("|", 2);
hf_EmployeeID.val(str[1]);
});
});
};
除了使用 ea_Autocomplete 类将两个输入包装在 div 中之外,我没有更改多视图中的任何内容,
<asp:Panel ID="eSearch" runat="server">
<b>Signup Employee Search</b> (<i>Last Name, First Name</i>)<br />
<div class="ea_Autocomplete">
<asp:TextBox ID="tb_EmployeeName" class="EmployeeSearch" runat="server"></asp:TextBox>
<asp:HiddenField ID="hf_EmployeeID" runat="server" />
</div>
<asp:Button ID="btn_Search" runat="server" Text="Search" />
</asp:Panel>
再次感谢 Nalum!
I have a Multiview search feature on a Web User Controller that is called within a Repeater, OHMY!!
I have some training sessions being listed out on a page, each calling an employeeSearch Web User Controller so people can search for employees to add to the training session. I have the Employee Names and Employee IDs listed out in JS on the page and using the jQuery autocomplete i have them search for the employee and populate a hidden field in the User controller. Once the process is done they have the option of adding yet another employee.
So i had Autocompelte 'work' in all the employee search boxes, but one i do the initial search (postback) autocomplete won't work again.
Then i updated $().ready(function() to pageLoad() so it works correctly on multiple searches but only in the LAST item of the repeater (jQuery is loaded on the User Controller)
FYI: I have the JS string set as EMPLOYEENAME|ID and jQuery displays the Employee Name and if they select it throws the ID in a ASP:HIDDEN FIELD
<script type="text/javascript">
format_item = function(item, position, length) {
var str = item.toString().split("|", 2);
return str[0];
}
function pageLoad() {
$("#<%=tb_EmployeeName.ClientID %>").autocomplete(EmployeeList, {
minChars: 0,
width: 500,
matchContains: true,
autoFill: false,
scrollHeight: 300,
scroll: true,
formatItem: format_item,
formatMatch: format_item,
formatResult: format_item
});
$("#<%=tb_EmployeeName.ClientID %>").result(function(event, data, formatted) {
var str = data.toString().split("|", 2);
$("#<%=hf_EmployeeID.ClientID %>").val(str[1]);
});
};
</script>
I can already guess that by repeating pageLoad within the User Controll i override the previous pageLoad.
THE QUESTION: Is there a way around this, a way to have all the jQuery appear in a single pageLoad or to somehow have a single jquery call to handle all my search boxes?
I can't move the jQuery into the page calling all the controllers because i have no way of referencing the specific tb_EmployeeName textbox AND hf_EmployeeID hidden field.
Thank you so much for any help or insight you can give me into this problem.
This is the Multiview that on the User Controller
<asp:MultiView ID="mv_EmployeeArea" runat="server" ActiveViewIndex="0">
<asp:View ID="vw_Search" runat="server">
<asp:Panel ID="eSearch" runat="server">
<b>Signup Employee Search</b> (<i>Last Name, First Name</i>)<br />
<asp:TextBox ID="tb_EmployeeName" class="EmployeeSearch" runat="server"></asp:TextBox>
<asp:HiddenField ID="hf_EmployeeID" runat="server" />
<asp:Button ID="btn_Search" runat="server" Text="Search" />
</asp:Panel>
</asp:View>
<asp:View ID="vw_Confirm" runat="server">
<b>Signup Confirmation</b>
<asp:FormView ID="fv_EmployeeInfo" runat="server">
<ItemTemplate>
<%#(Eval("LastName"))%>, <%#(Eval("FirstName"))%><br />
</ItemTemplate>
</asp:FormView>
<asp:Button ID="btn_Confirm" runat="server" Text="Signup this employee" /> <asp:Button ID="btn_Reset3" runat="server" Text="Reset" />
</asp:View>
<asp:View ID="vw_ThankYou" runat="server">
<b>Thank You</b><br />
The employee has been signed up and an email confirmation has been sent out.<br /><br />
<asp:Button ID="btn_Reset" runat="server" Text="Reset" />
</asp:View>
</asp:MultiView>
------------UPDATE-------------
Thanks to Nalum i was able to solve the problem in a much better fashion then my previous (deleted) try. Now i have a single function that handles all instances for the searchbox without having to generate more code for each searchbox being created.
The following javascript is being called on the parent page that contains the repeater.
format_item = function(item, position, length) {
var str = item.toString().split("|", 2);
return str[0];
}
function pageLoad() {
$(".ea_Autocomplete").each(function(i, element) {
var tb_EmployeeName = $(this).children('input[id*=tb_EmployeeName]:first')
var hf_EmployeeID = $(this).children('input[id*=hf_EmployeeID]:first')
tb_EmployeeName.autocomplete(EmployeeList, {
minChars: 0,
width: 500,
matchContains: true,
autoFill: false,
scrollHeight: 300,
scroll: true,
formatItem: format_item,
formatMatch: format_item,
formatResult: format_item
});
tb_EmployeeName.result(function(event, data, formatted) {
var str = data.toString().split("|", 2);
hf_EmployeeID.val(str[1]);
});
});
};
I didn't change anything in the Multiview beyond wrapping the two inputs in a div with the class ea_Autocomplete
<asp:Panel ID="eSearch" runat="server">
<b>Signup Employee Search</b> (<i>Last Name, First Name</i>)<br />
<div class="ea_Autocomplete">
<asp:TextBox ID="tb_EmployeeName" class="EmployeeSearch" runat="server"></asp:TextBox>
<asp:HiddenField ID="hf_EmployeeID" runat="server" />
</div>
<asp:Button ID="btn_Search" runat="server" Text="Search" />
</asp:Panel>
Thanks again Nalum!

我在这里有点猜测,我真的不了解asp.net,所以如果我错了,请纠正我。
我假设多视图正在 asp.net 后台执行某种 ajaxy 类型的操作,在这种情况下,当您的搜索表单重新加载时,
jQuery.autocomplete
将不适用于新表单。不过,我刚才所说的很可能是完全错误的。
编辑我的第二条评论。
I'm kinda guessing here, I don't really know asp.net so correct me if I am wrong.
I'm assuming that multiview is doing some sort of ajaxy type thing in the background of asp.net in which case when your search form is reloaded the
jQuery.autocomplete
would not apply to the new form.More than likely I'm completely wrong in what I just said though.
Edit for my second comment.
