Javascript 清除草稿行后如何转到另一页？

我需要在清除所有草稿行但它不起作用时转到下一页。 在这里，我有代码，它是关于它的长，但它就像九倍相同的代码只是为另一个草稿行

var cleared = 0;

//scratchpad1

images[3] = "images/logo.jpg";
images[4] = "images/winner.png";
images[5] = "images/scratch-to-win.png";

index = Math.floor(Math.random() * images.length);

$('#nummer1').wScratchPad({
  scratchMove: function (e, percent) {
    console.log(percent);
    if (percent > 70)

这是我尝试过的，但没有成功。

“没有成功。”-怎么没有成功？你期望发生什么，你期望哪一位（几位）的代码能做到这一点，你尝试了什么？它应该会给出一个带有一些文本的警报，如果你点击ok，你会转到另一个页面。但是没有警报
