页面重新加载不会在Greasemonkey-Script中停止。 怎么了？

Question

I wrote a script in Greasemonkey to check if a button exists and then click it. Else to reload the page.

Problem: The Button is found and clicked correctly. The page should not reload anymore but keeps on reloading and reloading.

What could be wrong????

Here is the code of my script:

 (function() { 'use strict'; var zeilen = document.getElementsByClassName('content-card-entry fcb-row fcb-clear'); for (var i = 0; i < zeilen.length; i++) { var zeile = zeilen[i]; // Zeile mit Block if (zeile.children[0].children[0].innerHTML == "247") { //Den String der ID auslesen var IDString = zeile.children[0].children[0].id; //Den Identifikationsstring ctlxxx auslesen var ClickID = IDString.substr(42, 5); //Den ClickString zusammenbauen var anfang = "ctl00_ContentMiddle_TicketList1_GridView1_"; var ende = "_LinkButton1"; var clickstring = anfang+ClickID+ende; //Den Button suchen var element = document.getElementById(clickstring); //Wenn der Button vorhanden ist klicken und mir eine Nachricht senden element.click(); } else { location.reload(); } } })();

You loop over a set of elements, and do "click or reload the page" for each of them. That means unless every single one of those elements is the button you're looking for, you're gonna reload the page.

Put a return after element.click() , so that your entire function exits if the button is found, and put location.reload() after the for loop, so that it is only called if the for loop terminated without returning from the function.
