JSON 在 JavaScript 中重要，因其轻量、通用、易读，适用于数据交换、存储和传输。
为什么写这个文章，废话不多，直接近主题。
一、通用
一般采用jquery编写
var key = $('#'+"cyberwin_form_card_newadd").serialize();结果：
TotalPrice=300&TotalCount=20&Memo=&paymethod[1][paymethod_id]=1&paymethod[1][paymethod_price]=200&paymethod[2][paymethod_id]=2&paymethod[2][paymethod_price]=50&paymethod[3][paymethod_id]=7&paymethod[3][paymethod_price]=50
二、form 序列号数组
(function($){
$.fn.serializeJson=function(){
var serializeObj={};
var array=this.serializeArray();
$(array).each(function(){
if(serializeObj[this.name]){
if($.isArray(serializeObj[this.name])){
serializeObj[this.name].push(this.value);
}else{
serializeObj[this.name]=[serializeObj[this.name],this.value];
}
}else{
serializeObj[this.name]=this.value;
}
});
return serializeObj;
};
})(jQuery);
结果
但是有个问题
数组没有分开
三、多维数组转换json
<ul id="cyberwin_paymethod" class="cyberwin_paymethod">
<li><select class="input_sijiao" name="paymethod[1][paymethod_id]" tips=""><option value="1">现金</option><option value="2">信用卡</option><option value="3">电子钱包</option><option value="4">会员卡</option><option value="5">积分</option><option value="6">挂帐</option><option value="7">赠卷</option></select><input class="input_sijiao paymethod_price" name="paymethod[1][paymethod_price]" value="300"><input class="input_sijiao paymethod_delete" type="button" onclick="fun_未来之窗_删除支付_内页frame(this)" value="x"></li>
<li><select class="input_sijiao" name="paymethod[2][paymethod_id]" tips=""><option value="1">现金</option><option value="2">信用卡</option><option value="3">电子钱包</option><option value="4">会员卡</option><option value="5">积分</option><option value="6">挂帐</option><option value="7">赠卷</option></select><input class="input_sijiao paymethod_price" name="paymethod[2][paymethod_price]" value="100"><input class="input_sijiao paymethod_delete" type="button" onclick="fun_未来之窗_删除支付_内页frame(this)" value="x"></li>
<li><select class="input_sijiao" name="paymethod[3][paymethod_id]" tips=""><option value="1">现金</option><option value="2">信用卡</option><option value="3">电子钱包</option><option value="4">会员卡</option><option value="5">积分</option><option value="6">挂帐</option><option value="7">赠卷</option></select><input class="input_sijiao paymethod_price" name="paymethod[3][paymethod_price]" value="50"><input class="input_sijiao paymethod_delete" type="button" onclick="fun_未来之窗_删除支付_内页frame(this)" value="x"></li>
</ul>
这种一般是3维数组
(function($){
//WLZC_serializeJson
//2024-2-29
$.fn.WLZC_serializeJson=function(){
var wlzc_serializeObj={};
var array=this.serializeArray();
$(array).each(function(){
var wlzc_ei_name = this.name;
//ymethod[1][paymethod_id]
var ie = wlzc_ei_name.indexOf("[");
if(ie >=0){
//console.log("未来之窗编码，存在" + wlzc_ei_name);
var wlzc_ei_name_yh1 =wlzc_ei_name.replace(/]/g,"");
const wlzc_ei_name_Array = wlzc_ei_name_yh1.split("[");
//console.log("未来之窗编码，分组");
const wlzc_ei_len = wlzc_ei_name_Array.length;
console.log(wlzc_ei_name_Array);
if(wlzc_ei_len == 3){
var array_1 =wlzc_ei_name_Array[0];
var array_2 =wlzc_ei_name_Array[1];
var array_3 =wlzc_ei_name_Array[2];
//错误 wlzc_serializeObj[array_1][array_2][array_3]=this.value;
//var jsonobj = array_2[array_3]=this.value;
var jsonobj_3=Array();
jsonobj_3[array_3]=this.value;
//console.log("未来之窗编码，分组jsonobj_3");
//console.log(jsonobj_3);
var jsonobj_2=Array();
jsonobj_2[array_2] = jsonobj_3;
//console.log("未来之窗编码，分组jsonobj_2");
//console.log(jsonobj_2);
//wlzc_serializeObj[array_1]=jsonobj_2;
if(wlzc_serializeObj[array_1]){
}else{
// wlzc_serializeObj[array_1]=[];
wlzc_serializeObj[array_1]={};
}
if(wlzc_serializeObj[array_1][array_2]){
}else{
// wlzc_serializeObj[array_1][array_2]=[];
wlzc_serializeObj[array_1][array_2]={};
}
if(wlzc_serializeObj[array_1][array_2][array_3]){
wlzc_serializeObj[array_1][array_2][array_3]=this.value;
}else{
wlzc_serializeObj[array_1][array_2][array_3]=this.value;
}
}
}else{
//未来之窗
if(wlzc_serializeObj[this.name]){
if($.isArray(wlzc_serializeObj[this.name])){
wlzc_serializeObj[this.name].push(this.value);
}else{
wlzc_serializeObj[this.name]=[wlzc_serializeObj[this.name],this.value];
}
}else{
wlzc_serializeObj[this.name]=this.value;
}
}
});
return wlzc_serializeObj;
};
})(jQuery);
结果输出
已经正常显示为json
四、将json对象转换为json字符串
var key=JSON.stringify(param4);;
