Answer 1

You should use the event onBlur tied to the field "pass2" in order trigger the first code snippet attached to your question.

For example:

document.getElementById("pass2").onblur=function(){
    var pass1 = document.getElementById("pass1").value;
    var pass2 = document.getElementById("pass2").value;
    if (pass1 != pass2) {
      document.getElementById("pass1").innerHTML="password must be match";
      document.getElementById("pass2").innerHTML="password must be match";
      document.getElementById("pass1").style.color="RED";
      return false;
     }
     return true;    
};

Another option is to tie it to the submit button.

添加一个div来存储对<div id='validate'></div>类的文档的密码验证响应，然后在检查密码是否匹配后，可以在此div document.getElementById('validate').innerHTML="passwords do not match!";的html中显示适当的结果.getElementById document.getElementById('validate').innerHTML="passwords do not match!";
