更改表格中第一行的背景颜色
下面是我的表格,其中填充了 spry 数据集
这是我的数据集
var ds1 = new Spry.Data.XMLDataSet("/xml/data.xml", "rows/row");
这是我的 jquery 在按钮上调用的方法中 单击
function addRow()
{
var newRow = new Array();
var nextID = ds1.getRowCount();
newRow['ds_RowID'] = nextID;
newRow['id'] = "x";
newRow['name'] = "Abhishek";
newRow['country'] = "India";
ds1.dataHash[newRow['ds_RowID']] = newRow;
ds1.data.push(newRow);
Spry.Data.updateRegion(ds1);
ds1.sort('name','descending');
ds1.setCurrentRow(newRow.ds_RowID);
$(".trEven td").css("background-color", "red");
alert($.fn.jquery);
/*$("#tableDg tbody tr:first").css({
"background-color": "red"
});*/
}
这是我的表格
<div id="cdiv" style="width:100%;" spry:region="ds1">
<table id="tableDg"
style="border:#2F5882 1px solid;width:100%;" cellspacing="1" cellpadding="1">

<th width="10%" align="center" spry:sort="name"><b>Name</b></th>
<th width="22%" align="center" spry:sort="host"><b>Country</b></th>
</tr>
</thead>
<tbody spry:repeat="ds1">
<tr id="trOdd"
spry:if="({ds_RowNumber} % 2) != 0" onclick="ds1.setCurrentRow('{ds_RowID}');"
style="color :#2F5882;background-color: #FFFFFF" class="{ds_OddRow}">
<td><input type="checkbox" id="chkbTest" class = "chkbCsm"></input></td>
<td width="10%" align="center"> {name}</td>
<td width="22%" align="center"> {country}</td>
</tr>
<tr id="trEven"
spry:if="({ds_RowNumber} % 2) == 0" onclick="ds1.setCurrentRow('{ds_RowID}');"
style="color :#2F5882;background-color: #EDF1F5;" class="{ds_EvenRow}">
<td><input type="checkbox" class = "chkbCsm"></input></td>
<td id="tdname" width="10%" align="center"> {name}</td>
<td width="22%" align="center"> {country}</td>
</tr>

</div>
我在哪里出错了,请指导我。谢谢 :)
Below is my table that is getting populated with spry dataset
Here is my dataset
var ds1 = new Spry.Data.XMLDataSet("/xml/data.xml", "rows/row");
Here is my jquery inside a method that is called on a button click
function addRow()
{
var newRow = new Array();
var nextID = ds1.getRowCount();
newRow['ds_RowID'] = nextID;
newRow['id'] = "x";
newRow['name'] = "Abhishek";
newRow['country'] = "India";
ds1.dataHash[newRow['ds_RowID']] = newRow;
ds1.data.push(newRow);
Spry.Data.updateRegion(ds1);
ds1.sort('name','descending');
ds1.setCurrentRow(newRow.ds_RowID);
$(".trEven td").css("background-color", "red");
alert($.fn.jquery);
/*$("#tableDg tbody tr:first").css({
"background-color": "red"
});*/
}
Here is my table
<div id="cdiv" style="width:100%;" spry:region="ds1">

如果我没记错的话,
只是描述结构。
表示表格的可视部分。或者这就是某些浏览器呈现它们的方式。
因此
$("#trEven td").css("background-color", "red")
应该可以工作。在可能存在多个实例的情况下,最好使用类而不是 id。If I remember right,
<tr>
is only describing structure.<td>
represents visual part of the table. Or this is how some browsers renders them.Therefore
$("#trEven td").css("background-color", "red")
should work. And preferrably you should use classes instead of ids in these kind of cases where there may exist multiple instances.适用于我(jsFiddle)。您遇到什么问题?
如果您使用类而不是 id,则可以使用类似以下内容的内容:
请参阅参考: jQuery API - .each( )
Works for me (jsFiddle). What problems are you experiencing?
If your use classes instead of id's, you can use something like the following:
See for reference: jQuery API - .each()
您不应该对奇数行和偶数行使用
id
。id
值在页面内是唯一的。所以,我建议:
然后:
然后:
如果您真的只想让表格主体中的第一行获得红色背景(而不是所有偶数背景),那么您的选择器应该是:
You shouldn’t be using
id
s for odd and even rows.id
values are meant to be unique within the page.So, I’d suggest:
and:
and then:
If you really only want the first row in the table body to get a red background (as opposed to all the even ones), then your selector should be:
