用图像按钮调用js函数用php而不提交

已采纳

Im coding php and i want to use image-button to call function.

$del= "<input type='image' src='delete.png' name='delete_cat' value='{$cat_name}' onclick='delete_exe(this.form,this.name,this.value)'  >";

This button is into a submit form

<form method="post" action="caffe_menu_category_post.php">

/form>

My problem is that when js function(delete_exe()) call and execute, then have auto-submit. I don't want that. Is there any solution or alternative code? Can i set submit off for my button?

Thanks in advance.

ps in my code i submit form with submit input

input type = "submit" value = "Submit Your Entries">

    Ok. i find the solution. I change my post form

    form name="myForm" method="post" action="caffe_menu_category_post.php" onsubmit="return validateForm()">

    And use javascripts

    var val=true;
        function delete_exe(sel,kind,name){
                //Set val false to stop submit
                val=false;                          
        }


    function validateForm(){
        if(!val){
            //Stop submit
            return false;
            }
        }

    So the auto-submit stop. On the oher hand when click submit button i call js function to set val=true;

    i don't know if these is the best solution, but it's work for me!

    Use 

    return false;

    in the end of your delete_exe(); function. That will cancel submitting.
