使用 window.find() 进行环绕搜索不起作用 [英] Wrap around search with window.find() doesn't work

问题描述

我正在尝试使用 window.config() 函数通过按钮触发搜索.但是，环绕布尔值设置为 true 但实际上不起作用...

I'm trying to use the window.config() function to trigger search with a button. However, the wrap around boolean is set on true but doesn't actually work...

语法:window.find(aString, aCaseSensitive, aBackwards, aWrapAround, aWholeWord, aSearchInFrames, aShowDialog);

我的代码:window.find(text, false, false, true, false, false, false);

你有什么想法吗?谢谢:)

推荐答案

事实上，您的问题是您正在调用 .find() 方法 在 container 而不是 window 元素，这就是它不起作用的原因，因为它是 window 对象的一部分，并且无法在 HTML 对象上访问.

In fact your problem is that you were calling .find() method on container instead of window element, that's why it isn't working because it's part of windowobject and is not accessible on HTML objects.

只需将您的代码更改为:

Just change your code to:

 if (window.find) {
  strFound = window.find(str);
  if (!strFound) {
   strFound = window.find(str, 0, 1);
   while (window.find(str, 0, 1)) continue;
  }
 }

演示:

这是一个工作演示以及您的更新的 CodePen.

This is a working demo along with your updated CodePen.

$('#search-btn').on('click', () => {
  findString('lorem')
});

function findString(str) {
  let strFound;
  if (window.find) {
    strFound = window.find(str);
    if (!strFound) {
      strFound = window.find(str, 0, 1);
      while (window.find(str, 0, 1)) continue;
    }
  }
  if (!strFound) alert("String '" + str + "' not found!")
  return;
}

#container {
  width:800px;
  height:200px;
  overflow:scroll
}
