首页 / 脚本样式 / JavaScript / jquery复选框CHECKBOX全选、反选

使用方法:我们先把下面的JS保存为有个文件,到时候调用,淡然你也可以直接写在页面内,推荐使用前者,方便重用:
复制代码 代码如下:
(function($){
$.fn.checkgroup = function(options){
//merge settings
settings=$.extend({
groupSelector:null,
groupName:"group_name",
enabledOnly:false
},options || {});

var ctrl_box=this;


//allow a group selector override option
var grp_slctr = (settings.groupSelector==null) ? "input[name="+settings.groupName+"]" : settings.groupSelector;

//grab only enabled checkboxes if required
if(settings.enabledOnly)
{
grp_slctr += ":enabled";
}

//attach click event to the "check all" checkbox(s)
ctrl_box.click(function(e){
chk_val=(e.target.checked);
$(grp_slctr).attr("checked",chk_val);
//if there are other "select all" boxes, sync them
ctrl_box.attr("checked",chk_val);
});
//attach click event to checkboxes in the "group"
$(grp_slctr).click(function(){
if(!this.checked)
{
ctrl_box.attr("checked",false);
}
else
{
//if # of chkbxes is equal to # of chkbxes that are checked
if($(grp_slctr).size()==$(grp_slctr+":checked").size()){
ctrl_box.attr("checked","checked");
}
}
});
//make this function chainable within jquery
return this;
};
})(jQuery);
主要看下面的使用方法:
复制代码 代码如下:
<input type="checkbox" class="checkall">checkall<br>
<input class="groupclass" name="group" type="checkbox">chk1<br>
<input class="groupclass" name="group" type="checkbox">chk2<br>
<input class="groupclass" name="group" type="checkbox">chk3<br>
<input class="groupclass" name="group" type="checkbox">chk4<br>
<input type="checkbox" class="checkall" id="checkall">
<?php
$(function() {
$("#checkall").click(function() {
$(".checkall").checkgroup({groupSelector:".groupclass",enabledOnly:true});
});
});

或者下面这种方式:

复制代码 代码如下:
<?php
$(function() {
$("#checkall").click(function() {
$("#checkall").checkgroup({groupName:"group"});
});
});
