how to differentiate between javascript triggered submit and manually clicking form submit
sample code below

 {
    document.getElementById("id_searchform").submit();
    return true;
 }

形式：

<div class='row'>
   <div class='col-md-4'>

   </div>
   <div class='col-md-4'>
      <div class='clstxtzipcode' ><input type="text" name="zip_code" id="txtZipcode"></div>
   </div>
   <div class='col-md-4'>
      <div class='clsbtnzip' ><input type="submit" name="submit" id="btnSearch" value="Search" class="button_example"  ></div>
   </div>
</div>
<a href="#"  onclick="return myfunction();" >click to submit</a>

推荐答案

让我看看我是否明白：

1. 您想要检测用户是否点击了提交表单的链接。


2. 您想要检测


3. 您有另一个名为 validate（）的函数，它将以某种方式使用这些信息。

1. You want to detect whether the user clicked the link to submit the form.
2. You want to detect if the user clicked the submit button to submit the form.
3. You have another function called validate() which will use this information in some way.

如果是这种情况，请考虑使用变量来存储链接是否在触发表单提交之前被点击。 p>

If this is the case, consider using a variable to store whether the link was clicked before triggering the form to submit.

1. 初始化全局变量 wasClicked 到 false


2. 点击链接时设置 wasClicked 到 true


3. 设置 wasClicked 后触发表单提交。


4. 运行 validate $ c> validate（）



1. Initialize global variable wasClicked to false
2. When link is clicked set wasClicked to true
3. Trigger form submit after wasClicked is set.
4. Run validate() when form is submitted
5. Check if(wasClicked){...} in validate()
