不要为 拼写 ajax url 而郁闷了。希望能对大家有帮助。
/*
1.form ajax 使用：
eG: form就是普通的 html form
<input type="button" value="xx" onclick="formAjax('data.jsp',this.form,ajaxReturn)"/>
function ajaxReturn(data){
document.getElementById("div1").innerHTML = data ;
}
2.ajax 使用 ：
AjaxFunction
AjaxFunction('url?param=tt¶m2=te',function(text){
alert(text);
});
3.迭代器：
recursiveNodes(array,dom,pushFun,layer)
array 迭代寄存器
dom 被迭代对象
pushFun 自定义收集方法
pushFun(array,node,layer)
node 迭代中对象
layer 深度
EG:
var arr = [] ;
recursiveNodes(arr ,dom,function(array,node,layer){
arr.push(node);
},2);
