我正在尝试在CLEL of LABEL上创建一个简单的SELECT ALL复选框。
但只有点击标签才能处理警报声明...... 在资产类型下的右侧，我点击了一个复选框，其中选中了所有复选框。但是可以通过点击标签来完成它而根本没有复选框......
Clear按钮也是一个问题，它是一个JQuery元素，点击它对复选框没有影响（理想情况下哪个必须提交）...
以下是代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="css/checkbox.css"/>

<script type="text/javascript">
$(document).ready(function() {
$('#selectAllTechAreas').click(function(){
alert('aaa');
$('.techAreasCheckBox').attr('checked', this.checked);
}); // Tech Areas Select All click function
$('#selectAllAssetTypes').tap(function(event){
/*$('.assetTypeCheckBox').attr('checked', this.checked);*/
/*alert("Select All Asset Types clicked");*/
$('.assetTypeCheckBox').attr('checked', this.checked);
}); // Asset Types Select All click function
$('#clearAllSelections').click(function(){
/*$('.techAreasCheckBox').attr('checked', this.checked);
$('.assetTypeCheckBox').attr('checked', this.checked);*/
// Problem with deselecting the HTML Checkbox with jQM element click
});
}); // document

似乎应该对您的代码进行非常小的更改...只是尝试将$('.techAreasCheckBox').attr('checked', this.checked);更改为$('.techAreasCheckBox').attr('checked', 'checked'); ...它适用于我:)并且还可以更改
$('#selectAllAssetTypes').tap(function(event){
$('.assetTypeCheckBox').attr('checked', this.checked);
.....
}
到
$('#selectAllAssetTypes').click(function(event){
$('.assetTypeCheckBox').attr('checked', 'checked');
.....
}
检查演示here并请注意我没有完成取消选择所有复选框的代码：）

您的主要问题在于：
$('.techAreasCheckBox').attr('checked', this.checked);
应该是
$('.techAreasCheckBox').attr('checked', true);
换句话说，就是设置checked属性的方式。
