The jquery setting button cannot be clicked to prevent repeated data submission

Form interaction is indispensable in web development. In reality, there is such a bug. After you fill out the form, click the submit button. If the website is slow, the page does not jump for half a day, you can click the submit button without stopping, causing data to be submitted repeatedly. This probability is not negligible. The author will share with you how to prevent repeated submission.

Simply put, after you click the submit button, if all the data passes the verification and is qualified, you can submit data and set the button to not clickable.

Code that cannot be clicked for the jquery setting button (the setting id = phpernote button cannot be clicked ):

$("#phpernote").attr("disabled",true);

Or

$("#phpernote").attr("disabled","disabled");

Code indicating that the javascript setting button cannot be clicked (the setting id = phpernote button cannot be clicked ):

<Input onclick = "document. getElementById ('phpernote '). setAttribute ('Disabled ', true); "type =" button "id =" phpernote "value =" Submit "/>
