Question

我有一个按钮，点击后调用 function1 调用另一个 function2 。如果function2满足条件，它应该返回false并在那里死亡但是它继续，返回到function1，执行其余的function1并提交表单。我是javascript的新手。

 <input type="button" value="Submit" onclick="function1()" />

 function function1() {
  function2();
  //execute rest of function
 }

 function2() {
 var this;
 var that;
 if(!this || !that) {
 alert("You did not fill out fields on the form under Tab1");
 return false;  //I thought it was supposed to stop here
 }
 }

Answer 1

在function1中调用function2时，如果你想让function1在函数2返回false时停止，那么你必须将它停在INSIDE函数1中，如下所示：

function function1() {
  // If function2 returns false, then stop function1
  if (!function2()) return;
  //execute rest of function
 }

 function2() {
  var this;
  var that;
  if(!this || !that) {
   alert("You did not fill out fields on the form under Tab1");
   return false;  //I thought it was supposed to stop here
  }
 }

提交表单即使我有＆＃34;返回false＆＃34;
