做后台系统的时候通常会用到form表单来做数据采集;每次一个字段一个字段的去收集就会很麻烦,网站也有form.js插件可以进行表单收集,并封装成一个对象,通过ajax方法传到后台;现在介绍一种直觉采集form表单的方式:
1.首先写一段公用的js:
//收集表单数据为一个数组
$.request = function (name) {
var search = location.search.slice();
var arr = search.split("&");
for (var i = ; i < arr.length; i++) {
var ar = arr[i].split("=");
if (ar[] == name) {
if (unescape(ar[]) == 'undefined') {
return "";
} else {
return unescape(ar[]);
}
}
}
return "";
}
$.fn.formSerialize = function (formdate) {
var element = $(this);
if (!!formdate) {
for (var key in formdate) {
var $id = element.find('#' + key);
var value = $.trim(formdate[key]).replace(/ /g, '');
var type = $id.attr('type');
if ($id.hasClass("select2-hidden-accessible")) {
type = "select";
}
switch (type) {
case "checkbox":
if (value == "true") {
$id.attr("checked", 'checked');
} else {
$id.removeAttr("checked");
}
break;
case "select":
$id.val(value).trigger("change");
break;
default:
$id.val(value);
break;
}
};
return false;
}
var postdata = {};
element.find('input,select,textarea').each(function (r) {
var $this = $(this);
var id = $this.attr('id');
var type = $this.attr('type');
switch (type) {
case "checkbox":
postdata[id] = $this.is(":checked");
break;
default:
var value = $this.val() == "" ? " " : $this.val();
if (!$.request("keyValue")) {
value = value.replace(/ /g, '');
}
postdata[id] = value;
break;
}
});
if ($('[name=__RequestVerificationToken]').length > ) {
postdata["__RequestVerificationToken"] = $('[name=__RequestVerificationToken]').val();
}
return postdata;
};
2.使用方法
html代码:
<form id='form1id'>
姓名:<input type='text' id='names' name='names'/><br/>
年龄:<input type='text' id='names' name='names'/>
</form> js代码:
var infoModel = JSON.stringify($("#form1id").formSerialize());//得到手机到的表对象
$.ajax({
type: "Post",
url: "/HRSSC/Resume/" + Act,
data: "{infoModel:" + infoModel + "}",//前面的命名和后台接收参数一直
dataType: "json",
contentType: "application/json",
success: function (result) {console.log(result);} 后台代码:
public ActionResult AddEmp(Empinfo infoModel) //命名和前台ajax传的参数一致
{
//具体业务处理
return view();
}
只要把form表单里面的字段和后台类字段对应,收集起来的对象在后台可以直接使用!
