javascript - Why does jQuery "toggle" button trigger the Submit button on a form? - Stack Overflow

文章数量:1241152

I have built a fairly plex form which includes a hidden section that the user can toggle open for entering more information if necessary. However, when you click on this toggle button labeled I have more Nativities, it triggers the submit button and prematurely submits the form.

The form is in dev right now, but it can be found here.

The code I am using for the toggle button is:

<script type="text/javascript">
    $(function() {
        $("#schedule").accordion({ header: "h5", collapsible: true });
        $("#more-nativities").hide();
        $("#toggle").click(function()   {
            $("#more-nativities").slideToggle("slow");
        });
    });
    </script>

The code for the submit button is pretty basic:

<input id="submit2" type="image" src="_images/btn_register.jpg" name="submit"  alt="" onmouseover="javascript:this.src='_images/btn_register2.jpg'" onmouseout="javascript:this.src='_images/btn_register.jpg'"/>

The code for the toggle button is:

<button id="toggle">I have more nativities</button>

Any ideas as to why the toggle button is triggering the submit? And more importantly how to solve the problem?

Thanks!

• 4 As an aside, I would suggest not using inline JS. Write unobtrusive Javascript. – Peter Ajtai Commented Sep 19, 2010 at 22:34
• It's very helpful to provide as much pertinent code as possible. I edited in your original code for the toggle button. – Peter Ajtai Commented Sep 19, 2010 at 22:46

Try adding a type, i.e.:

<button type="button" id="#toggle">Text</button>

http://www.w3schools./tags/tag_button.asp says this should be always defined. It's possible the browser is defaulting to a submit button.

Esteban has one solution. A better one is described in the jQuery tutorial:

 $(document).ready(function(){
   $("a").click(function(event){
     alert("As you can see, the link no longer took you to jquery.");
     event.preventDefault();
   });
 });

Try

 return false;

after the slide toggle on the click function fro the toggle button.

From W3Schools:

Always specify the type attribute for the button. The default type for Internet Explorer is "button", while in other browsers (and in the W3C specification) it is "submit".

Be sure to specify type="button"
