jquery is using the submit issue in form, not resolved

  $ ("#login_btn"). Click (function () {Type is the button under Submit    if ($ ("#id_password"). Val (). length = = 0) {// Verify that password is empty      $ (' form '). Submit (function () {        alert ("1")        return false;      });    else if ($ ("#vali"). val ()! = code) {//Verify that the code is correct      $ (' form '). Submit (function () {        alert ("2")        return false;      });    }else{      $ (' form '). Submit (function () {        alert ("3")        return true;}      );    }  );

When the test is found, when the password is empty, the popup 1, and then click once. Popped two times 1. Click again, pop up three 1; Enter password. Click again to find pop-up 1, 1. 1. 2, looking for a long time do not know why

Change strategy later

<pre name= "code" class= "HTML" >$ (' form '). Submit (function () {    var b = true;    if ($ ("#id_password"). Val (). length = = 0) {      $ ("#verify"). html (' <div class= ' alert alert-error ' > Please enter your password!</ Div> '). Show ();      b = false;    } else if ($ ("#vali"). val ()! = code) {      $ ("#verify"). html (' <div class= ' alert alert-error ' > CAPTCHA input Error!</div> '). Show ();      b = false;    } else{      B = true;    }      return b;  });

So that I can, I don't know why ~ ~ ~ Ask for answers
