js:
var tota = $(".proAll .pro-item").length;
var JsonData = {
a: "",
b: "",
c: ""
}
var aa = [];
for(var i = 0; i < tota; i++) {
var JsonData = new Object();
JsonData.a = $(".proImg").eq(i).attr("src");
JsonData.b = $(".proTitle").eq(i).html();
JsonData.c = $(".url").eq(i).attr("href");
aa.push(JsonData);
}
var json = JSON.stringify(aa);
console.log(json);
前端调用的时候，要转换：
var data = $.parseJSON(json);//
