jquery--各种小技巧集合
1.获得所有选中的checkbox的方法
//根据传入的checkbox的name获得所有checkbox选取的的值
function addMem(names){
var allNames=0;
$("input[name='"+names+"']").each(function(){
if($(this).attr("checked")=="checked"){
if(allNames==0){
allNames=$(this).attr("value");
}else{
allNames += ","+$(this).attr("value");
}
}
});
alert(allNames);
return allNames;
}
2.复选框全部选定或者全部不选定
function selectAll(){
$("#deleteAll").change(function(){
if($(this).attr("checked")=="checked"){
$("input[name='deleteCheck']").each(function(){
$(this).attr("checked",true);
});
}else{
$("input[name='deleteCheck']").each(function(){
$(this).attr("checked",false);
});
}
});
}
3.另一种全选，全不选，反选的方式（与原生js混合使用）

<script language="javascript" src="../css02/js/jquery-1.6.1.js"></script>
<script>
$(document).ready(function(){
$("#selectAll").click(function(){
//这里也可以直接用this,原生js语句
if($(this)[0].checked){
$('[name=items]:checkbox').attr("checked",true);
}else{
$('[name=items]:checkbox').attr("checked",false);
}
});
$("#XOR").click(function(){
$("[name=items]:checkbox").each(function(){
this.checked=!this.checked;
});
});
});
</script>
<title>Untitled Document</title>
</head>
<body>
<input type="checkbox" name="items" value="足球" />足球
<input type="checkbox" name="items" value="足球" />足球
<input type="checkbox" name="items" value="足球" />足球
<input type="checkbox" name="items" value="足球" />足球
<input type="checkbox" id="selectAll" value="全选/不选"/>全选/全部选
<input type="button" id="XOR" value="反选"/>
</body>
</html>
4.表格分层折叠

<script>
$(function(){
$('tr.parent').click(function(){
$(this).toggleClass("selected").siblings('.child_'+this.id).toggle();
});
});
</script>
<style>
.selected{background:red};
</style>
<title>Untitled Document</title>
</head>
<body>
<table>

<script>
$(function(){
$("#confirm").click(function(){
var txt=$("[name=fileterText]").val();
//思路是先全部隐藏，然后根据内容再显示出来
$("table tbody tr").hide().filter(":contains("+txt+")").show();
});
});
</script>
<style>
.selected{background:red};
</style>
<title>Untitled Document</title>
