The general principle is: Listen to the pasting time, check whether there is an image, and then trigger AJAX upload. The receiving principle of PHP is consistent with that of file upload.

  
Script // search for the box element to check the document. querySelector ('# box '). addEventListener ('paste ', function (e) {// determine whether the image is pasted if (e. clipboardData & e. clipboardData. items [0]. type. indexOf ('image')>-1) {var that = this, reader = new FileReader (); file = e. clipboardData. items [0]. getAsFile (); // ajax uploads an image reader. onload = function (e) {var xhr = new XMLHttpRequest (), fd = new FormData (); xhr. open ('post', '', true); xhr. onload = function () {var img = new Image (); img. src = xhr. responseText; // that. innerHTML = ''; document. getElementById ("img_puth "). value = img. src;} // this. result to get the base64 (which can be used for instant display) fd of the image. append ('file', this. result); that. innerHTML = ''; xhr. send (fd);} reader. readAsDataURL (file) ;}}, false); script
