根据多个项目需求,这个小功能有必要封装一个js插件,需要地方随时引入使用即可

话不多说先看效果:

优点:无需写其他代码,就只需要引用js和调用即可;

缺点:代码优化不够精简,配置项不够强大;


使用如下:

MpName: ""//公众号名称
QrCodeUrl: ""//二维码地址
Type: 0//按钮显示内容 1 文字类型  2 二维码类型 0两种都显示(默认)

完整js代码

var IsSubscribe = {
    Par: {
        "MpName": "",//公众号名称
        "QrCodeUrl": "",//二维码地址
        "Type": 0,//按钮显示内容 1 文字类型  2 二维码类型 0两种都显示(默认)
    },
    Init: function (par) {
        if (par.MpName != null && par.MpName != undefined) {
            this.Par.MpName = par.MpName;
        }
        if (par.QrCodeUrl != null && par.QrCodeUrl != undefined) {
