通过div得到div里的所有数据
大神的世界无需解释，当然不是说我，当我看到这些代码的时候我惊呆了！
这是一个工具方法js：
js: /*
* 获取指定对象下的所有input、textarea值
* divid：外层的id
* jsonStr：如果无，新创建一个对象，如果有，直接在对象中添加
* isCheck:是否进行必填项判断
*/
getFormParam: function(divid,jsonStr,isCheck){
var inputlist = $("#"+divid+" input[type=text]");
var textarealist = $("#"+divid+" textarea");
var param = {};
if(jsonStr){
param = jsonStr;
} var iserror =false;
$.each(inputlist,function(i,obj){
var id = obj.id;
var name = obj.name;
if(!id && !name){ }else{
var ligeruiid = obj.attributes.ligeruiid;
var val = $.trim(obj.value);
if(val == ''){
if(isCheck && $(obj).attr("isrequired") == ''){
if(obj.style.display == 'none' || (obj.parentNode && obj.parentNode.style.display == 'none')){//父节点是否隐藏 }else{
iserror =true;
obj.style.border = '1px dotted #FF0000';
//$(obj).attr({"style":"border: 1px dotted #FF0000;"});
}
}
}else{
obj.style.border = '';
}
if(ligeruiid){
val = $("#"+id+"_hidden").val();
}
if(name){
param[name] = val;
}else{
param[id] = val;
}
}
});
$.each(textarealist,function(i,obj){
var id = obj.id;
var name = obj.name;
if(!id && !name){ }else{
var val = $.trim(obj.value);
if(val == ''){
if(isCheck && $(obj).attr("isrequired") == ''){
if(obj.parentNode && obj.parentNode.style.display == 'none'){//父节点是否隐藏 }else{
iserror =true;
obj.style.border = '1px dotted #FF0000';
//$(obj).attr({"style":"border: 1px dotted #FF0000;"});
}
}
}else{
obj.style.border = '';
}
if(name){
param[name] = val;
}else{
param[id] = val;
}
}
});
if(iserror){
return 'error';
}
return param;
}

将div里的值获取后传向后台：
var jsonStr;
jsonStr = globalUtil.getFormParam('main_t',null,false);
$("#tb_btn").css("display","none");//隐藏按钮
$.post(globalUtil.getTimestampUrl("/cremanage/mcscrecreditheadupdate.do"),
jsonStr, function(data) {
if (data === 'OK') {
globalUtil.successMsg(globalErrorMsg[''],
function() {
//关闭TAB 刷新列表
closeTabAndRes();
});//保存成功
}else {
globalUtil.errorMsg(globalErrorMsg['']); //保存失败
$("#tb_btn").css("display","");//显示按钮
}
});
