我想将文本与动态复选框匹配。这意味着如果我在文本框中写入 H，那么它将显示其中包含 H 的所有复选框。这是我的适用于静态代码的代码但不适用于动态请帮助我，我是 jquery 和 java 脚本的新手
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<meta charset="utf-8" />
<script type="text/javascript"> $(function () {
$('#chkfilter').on('keyup', function () {
var query = this.value;
$('[id^="chk"]').each(function (i, elem) {
if (elem.value.indexOf(query) != -1) {
$(this).closest('label').show();
} else {
$(this).closest('label').hide();
}
});
});
});</script>
<style>
input
{
display: inline;
}
</style>
<title></title>
</head>
<body>
<form id="form1" runat="server">
<label>
<input type="checkbox" name="chk" id="chk1" value="casual">casual</label><br>

静态代码
当我将其转换为动态复选框时，将显示其值，但当我尝试匹配它时，它不起作用

最佳答案
您可以将复选框包装在容器中，使用该容器的 ID 来获取所有复选框。
<div id="checkBoxList">
<label>
<input type="checkbox" name="chk" id="chk1" value="casual">casual</label><br>
<label>
<input type="checkbox" name="chk" id="chk2" value="intermediate">intermediate</label><br>
</div>
然后更改 JavaScript 中的行
$('[id^="chk"]').each(function (i, elem) {
到此
$('#checkBoxList input[type="checkbox"]').each(function (i, elem) {
Ps，您的函数不再工作的原因是 objcolor.ListclsColor[i].ColorID 可能不包含 chk
