How To Make Phantomjs Wait For A Specific Condition On The Page

I want to realize something like this: function(){ var ua = page.evaluate(function() { while (document.getElementById('td_details87').parentElement.children[11].textC

Solution 1:

There is no blocking sleep() function in JavaScript. If you want to sleep then you have to use some asynchronous function like setTimeout(callback, timeout).

There is a function in the examples folder of PhantomJS that does what you're trying to do. It's waitFor(testFx, onReady[, timeout]). It works by calling the test function over and over again until it returns a truthy value.

In your case that would look like this:

waitFor(function_test(){
    return page.evaluate(function() {
        returndocument.getElementById("td_details87").parentElement.children[11].textContent == "Running"; 
    });
}, function_onReady(){
    console.log ("DONE");
});
