javascript - 如何循环绑定事件？在借款协议处绑定url（DATA.argeement），点击可以跳转至网址

1.想要给每个借款协议绑定不同URL，就是data里面的argeement,点击跳转至不同 url该如何做？我为何 var url=$(".argeement").attr("class");console.log(url); 是undefined

    1. 你 agreement 很多地方打錯成 argeement....

    2. 你是把網址給取代 class="$agreement$" 所以並不會有 .agreement 存在

    3. 強烈建議這種額外數據不要存在 class 中，可以存在 data-url，但在這裡還是把元素改
      成 a 放進 href 最直觀

    4. FastClick 的用法錯了，下面有改過後的～

    下面是修改過後的代碼：

  FastClick.attach(document.body)

  var dataJSON = JSON.parse(DATA);
      var sort = dataJSON.sort( function(a, b) {

   });

  dataJSON.forEach(function(item) {
      var tplReplace = template.replace("$amount$", item.amount)
      .replace("$status$", item.status.toLowerCase())
      .replace("$status$", function(){
           if(item.status == "IN_PROGRESS"){
               return 　"进行中"
           }
           else{

           }
       })
      .replace("$loan_time$",item.loan_time)
      .replace("$loan_limited$",item.loan_limited)
      .replace("$payed$",item.payed)
      .replace("$agreement$",item.agreement)
      .replace("$load_no$",item.load_no);

  })
