Jquery checkbox級聯選擇 -- 通用型
[javascript]
/*
checkbox 上需要添加index字段 格式如下：父節點為1則子節點為1_1，1_2 以此類推
*/
$j(function($) {
$(":checkbox").click(function(){
var index = $(this).attr("index");
$(":checkbox[index^="+index+"]").attr("checked",$(this).is(":checked"));
var parent_index = index.substring(0,index.length - 2);
$(":checkbox[index="+parent_index+"]").attr("checked",false);
var parentIsCheck = false;
$(":checkbox[index^="+parent_index+"]").each(function(i){
if($(this).is(":checked")){
parentIsCheck = true;
}
});
$(":checkbox[index="+parent_index+"]").attr("checked",parentIsCheck);
var parent_parent_index = index.substring(0,parent_index.length - 2);
var parent_parent_is_check = false;
$(":checkbox[index="+parent_parent_index+"]").attr("checked",parent_parent_is_check);
$(":checkbox[index^="+parent_parent_index+"]").each(function(i){
if($(this).is(":checked")){
parent_parent_is_check = true;
}
});
$(":checkbox[index="+parent_parent_index+"]").attr("checked",parent_parent_is_check);
});
});
關鍵在於index 這個字段 -- js代易做图只不過是判定而已~~~
