当我出局时如何打破循环？

Question

Here is my code:

$(document).on('click', '.fa-search', function () {

    while(1) {
        magnifire.fadeTo('slow', 0.2).fadeTo('slow', .8);
    }
    sendAjaxRequest();

    // Here I need to break (stop) that while loop
})

As I've commented in my code, I need to stop while(1) after sendAjaxRequest(); executed. How can I do that?

You could use setInterval and clearInterval for this. As their names suggest, setInterval sets a function to execute repeatedly at given interval (1000 ms in example below), and clearInterval stops all further executions.

 var interval = setInterval(function() { console.log("Do something"); // magnifire.fadeTo('slow', 0.2).fadeTo('slow', .8); },1000); function Clear() { clearInterval(interval); console.log("Stop iterating"); } 

 <button onclick="Clear()">Click me</button>
