更新 - 我已解决了问题

我发现了问题,post_max_size php.ini的属性设置为8MB。将其更改为20MB后,一切正常。感谢您在代码中指出一些语法问题。

我在页面的body标签中有这段代码:

            });
        }
    });
</script>

问题是我的帖子“如果一切正常就会执行POST”如果我正在使用var returnVar = <?php echo $newJobName; ?>或var {{1执行的功能>发送空参数有} returnVar = <?php echo $jobsArray[2]; ?>.apply(this, vars);var maxNum = 500000;。当我在POST的参数窗口下查看控制台到var arrayMaxSize = 500000;时,我正确的结果就是不在视图窗口上,当然也没有在得到的job.php页面本身。 这是var returnVar

调用的函数
executedJobs.php

有趣的是,对于function job1() { var notSortNumArray = []; var notSorted1 = []; var notSorted2 = []; var maxNum = 500000; var arrayMaxSize = 500000; var minNum = 1; // create an array with arrayMaxSize random nmber between minNum and maxNum for (var x = 0; x < arrayMaxSize; x++) { notSortNumArray.push(Math.floor(Math.random() * (maxNum - minNum)) + minNum); } // The notSorted1 is from possition 0 untill random between 0 and arrayMaxSize notSorted1 = notSortNumArray.slice(0, Math.floor(Math.random() * notSortNumArray.length)); // The notSorted2 is from where the notSorted1 ends untill the last number form the notSortNumArray notSorted2 = notSortNumArray.slice(notSorted1.length, notSortNumArray.length); // job dependencies var nextJob = "job2, job3"; var prevJob = "null"; // results return [ notSortNumArray, arrayMaxSize, notSorted1, notSorted2 ]; } var maxNum = 250000;,一切都运作良好,所有结果都会发送到var arrayMaxSize = 250000页面以供进一步使用。

我再次希望有人可以帮助我解决这个问题,因为我不知道为什么它不适用于更高数量的executedJobs.phpvar maxNum参数,结果是他们和某些东西正被发送到得执行的.Jobs.php页面但没有任何结果。

我知道这是很多代码,但我希望有人可以帮我解决这个问题,因为我不知道为什么它不起作用。

答案 0 :(得分:0)

行上没有分号:

var scriptPath = "<?php echo $jobJSPath[0]; ?>" 
var execMessage = "An unknown falure has accourd while executing, will be executed once more"

排队:

var hasOutput = <?php echo json_encode($allOutputVarName);?>;

你应该把它改成:

var hasOutput = JSON.parse("<?php echo json_encode($allOutputVarName);?>");
