小程序多个formid写法

---

---

Tip：这个e.detail.fromId，就是formid，真机才会产生，模拟器中为“the formId is a mock one”

wxml布局

<form bindsubmit="goto_index" report-submit="true">
    <button class="form_button" form-type="submit">
        <image src="../../img/tx.jpeg" mode="aspectFit" >image>
    button>
form>

清除button默认样式，通用

button.form_button{background-color:transparent;padding:0;margin:0;display:inline;position:static;border:0;padding-left:0;padding-right:0;border-radius:0;font-size:0rpx;color:transparent;}

button.form_button::after{content:'';width:0;height:0;-webkit-transform:scale(1);transform:scale(1);display:none;background-color:transparent;}

js

goto_index:function(e){
  //获取点击formid
  console.log(e.detail.formId)
}
