Prevent href double click

IamtheWalrus

I have a href in a Jsp page that, when clicked, navigates the page to another page and calls a Java method. If you double click the href, the page navigates but the Java method is called twice. This is undesirable.

Has anyone any suggestion on how to stop this? I've tried many internet suggestions but none have worked.

Use jquery to remove the href attribute of the link after the user clicks on it

JavaScript solutions I've used in the past involve replacing the link with a "Loading, please wait" graphic when it's clicked the first time.

The ideal solution would be to detect double-clicks in the target page and abort one of them. Javascript solutions alone aren't ideal.

You could also consider implementing a nonce (single use token) as well as the (client side) JavaScript. Some MVC frameworks have built in support for this.

I had thought of that but it's not as easy as that.

Here is my code. I loop through a collection of products and displaying each record in a table. So each TR will be converted into a link, as follows:

<tr id="x" data-href="${flowExecutionUrl}&_eventId=getProductDetails()">

As you can see, I use a thing called data-href, which basically resolves to a href.

for the client side have the href call a function passing the different params for each TR
Within the function only allow single processing (if you are using ajax to call the backend for example) or just remove/hide/prevent all the other rows from being clickable

but you should ideally couple this with a backend solution as advised above
