基于jQuery的一个扩展form序列化到json对象

复制代码 代码如下:

$.fn.serializeObject = function() {
var o = {};
var a = this.serializeArray();
$.each(a, function() {
if (o[this.name]) {
if (!o[this.name].push) {
o[this.name] = [ o[this.name] ];
}
o[this.name].push(this.value || '');
} else {
o[this.name] = this.value || '';
}
});
return o;
}

复制代码 代码如下:

<form id="testform">
<input type="text" name="name" value="dummyName" id="name">
<input type="text" name="category.id" value="categoryId" id="name">
<input type="text" name="category.name" value="categoryName" id="name">
</form>

复制代码 代码如下:

public class DummyProduct {

private DummyCategory category;
private String name;

public DummyCategory getCategory() {
return category;
}
public void setCategory(DummyCategory category) {
this.category = category;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}

}
public class DummyCategory {
private String id;
private String name;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}

复制代码 代码如下:

/** @serializedParams looks like "prop1=value1&prop2=value2".  
Nested property like 'prop.subprop=value' is also supported **/
function paramString2obj (serializedParams) {

var obj={};
function evalThem (str) {
var attributeName = str.split("=")[0];
var attributeValue = str.split("=")[1];
if(!attributeValue){
return ;
}

var array = attributeName.split(".");
for (var i = 1; i < array.length; i++) {
var tmpArray = Array();
tmpArray.push("obj");
for (var j = 0; j < i; j++) {
tmpArray.push(array[j]);
};
var evalString = tmpArray.join(".");
// alert(evalString);
if(!eval(evalString)){
eval(evalString+"={};");
}
};
eval("obj."+attributeName+"='"+attributeValue+"';");

};
var properties = serializedParams.split("&");
for (var i = 0; i < properties.length; i++) {
evalThem(properties[i]);
};
return obj;
}
$.fn.form2json = function(){
var serializedParams = this.serialize();
var obj = paramString2obj(serializedParams);
return JSON.stringify(obj);
}

复制代码 代码如下:

var json = $("#testform").form2json();
alert(json);
