How to disable submit push using JavaScript
You don't need to practice a lot but add together this.disabled='disabled' on onclick effect handler of push similar below:
<form action="submit.jsp" method="post" >

</form>
This JavaScript code volition disable submit push in 1 lawsuit clicked. Instead of this, which correspond electrical flow chemical ingredient similar to Java this keyword, You tin terminate equally good purpose document.getElementById('id') but this is brusque in addition to clear.
Now about browser has occupation to submit information from disabled button. So, its amend to telephone telephone form.submit() from onclick itself to submit shape data, which makes your code to onclick="this.disabled=true;this.form.submit(). Particularly, on Internet Explorer a disabled submit push doesn't submit shape information to server. You tin terminate equally good modify value or text of submit push from submit to "Submitting...." to bespeak user that submit is inwards progress. Final JavaScript code should human face like:
<form action="submit.jsp" method="post" >

</form>
That's all you lot need to disable submit push using HTML in addition to JavaScript to forestall multiple submission.
Once you lot are comfortable alongside unproblematic means of disabling submit push you lot may larn in addition to explore multiple ways to forestall multiple shape submissions or disable submit button. As I said if you lot are beginner to JavaScript or HTML than it takes about fourth dimension to larn concord of these tricks. If you lot are using Internet explorer in addition to non calling this.form.submit() in addition to thence alone push volition last disabled but shape volition non last submitted thence ever telephone telephone this.form.submit().
form.submit() doesn't include submit push nurture inwards request
There is a caveat spell using JavaScript to submit form, it doesn't include nurture of submit push equally asking parameter. If you lot are checking for nurture of submit push on server side your code volition fail. For example, next code which is checking for SUBMIT push equally asking parameter using Spring MVC WebUtils class. if(WebUtils.hasSubmitParameter(request, "SUBMIT")){
//form has been submitted offset processing.
}
This code volition neglect if shape is submitted yesteryear this.form.submit(), rather than clicking submit button. Traditionally nurture of submit push is included inwards HTTP asking alone if shape is submitted yesteryear clicking submit push otherwise no. Fortunately at that spot is a workaround to this problem, You tin terminate telephone telephone document.form_name.submit_name.click() to copy click on submit button. This volition include nurture of submit push in HTTP POST request and to a higher house Spring MVC instance volition operate equally expected. If you lot don't conduct maintain multiple buttons on hide in addition to alone conduct maintain 1 submit push than you lot tin terminate equally good purpose HTML hidden input plain to ship nurture of submit push equally shown inwards below example:
<input type="hidden" value="meta data" name="SUBMIT" id="submit_hidden" />
Since code is alone checking for whatsoever named parameter alongside nurture SUBMIT it volition work.
What if you lot conduct maintain multiple submit push inwards 1 screen
There are cases when you lot conduct maintain multiple HTML push inwards 1 hide similar "Accept" or "Decline", "Yes or "No" , Accept" or "Reject" etc. In this case, clicking 1 push should disable both buttons because at that spot are intended for 1 operation. In guild to disable multiple submit push inwards onclick, You need to explicitly disable those buttons. As inwards next example, if you lot conduct maintain ii buttons alongside nurture accept in addition to decline , nosotros are disabling both when whatsoever of the push larn clicked.
<input type="submit"
id="accept"
name="ACCEPT"
value="Accept"
onclick="this.disabled='disabled';
document.getElementById('reject').disabled='disable';
this.form.submit();" />
<input type="submit"
id="reject"
name="REJECT"
value="Reject"
onclick="this.disabled='disabled';
document.getElementById('accept').disabled='disable';
this.form.submit();" />
This code may larn clutter if you lot conduct maintain to a greater extent than than ii buttons in addition to its best to write JavaScript business office to disable all submit push on that group.
That’s all on How to disable submit push inwards HTML in addition to forestall multiple shape submissions on Server. Anyway at that spot are multiple ways to attain this, both on customer side in addition to server side. I prefer to practice this on customer side using JavaScript to avoid server circular trip.
