The first method: join in the direct button
When you click Submit, the Submit button becomes grayed out, which prevents duplicate submissions, and this code is the implementation of such a function. As you can see from the code, we just add this sentence to the submit button: onclick= "Javascript:{this.disabled=true;document.form1.submit ();", meaning that when the button is clicked, Set the unavailable property of the button to true so that the button becomes dimmed
<ptml> <pead> <meta http-equiv= "Content-type" content= "text/html; charset=gb2312 "> <title> form Submit button turns gray </title> </pead> <body> <form name=form1 method=" POST "action="/"target=_blank> <p><input type=" text "name=" T1 "size=" "><input type=" button "value = "Submit" onclick= "Javascript:{this.disabled=true;document.form1.submit ();}" > <input type= "reset" value= "reset" name= "B2" ></p> </form> </body> </ptml>
[Ctrl + A All SELECT Note: If the need to introduce external JS need to refresh to perform]
The second method is implemented by the OnSubmit event, and the dimmed button can be turned into usable
Add the OnSubmit event to the form, and if the form joins the judge, then the method can be used directly, remember to put it in the end, otherwise it would be grayed out at first, but we added a code that makes the Submit button available.
You can prevent duplicate submissions or prevent code problems from being uncommitted
Copy Code code as follows:
<form name=form1 action= "" onsubmit= "return Closebut ()" >
<input name= "ImageField" type= "Submit" class= "Inputbut" value= "OK"/><br>
<input type= "button" name= "hui" id= "hui" value= "make the Submit button available" onclick= "Document.form1.imagefield.disabled=false"/>
</form>
<script>
function Closebut () {
Document.form1.imagefield.disabled=true;
}
</script>
