问题描述
About this problem, I saw a some solution here at Stack Overflow and the solution redirects me here: http://jsfiddle.net/9hGym/ On JS fiddle, the code works but when I implement it on my editor and run it, it's not working. 
关于这个问题，我在Stack Overflow上看到了一些解决方案，该解决方案将我重定向到这里： http : //jsfiddle.net/9hGym/在JS小提琴上，代码可以工作，但是当我在编辑器上实现并运行它时，不工作。 By the way, as a library I used Google CDN, I don't know if it is proper way, so help me. 顺便说一句，作为一个图书馆，我使用Google CDN，我不知道这是不是正确的方法，所以请帮助我。 Here's my code by the way.. 这是我的代码。
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script language = "javascript">
// Write on keyup event of keyword input element
$("#search").keyup(function(){
_this = this;
// Show only matching TR, hide rest of them
$.each($("#table tbody").find("tr"), function() {
console.log($(this).text());
if($(this).text().toLowerCase().indexOf($(_this).val().toLowerCase()) == -1)
$(this).hide();
else
$(this).show();

You should place the javascript code within a $(document).ready, this will ensure the function is run after the DOM is ready. 您应该将javascript代码放在$（document）.ready内，这将确保在DOM准备就绪后函数可以运行。
<script language = "javascript">
$( document ).ready(function(){
// Write on keyup event of keyword input element
$("#search").keyup(function(){
_this = this;
// Show only matching TR, hide rest of them
$.each($("#table tbody").find("tr"), function() {
console.log($(this).text());
if($(this).text().toLowerCase().indexOf($(_this).val().toLowerCase()) == -1)
$(this).hide();
else
$(this).show();
});
});
});
</script>

You can try to use getElementsByTagName , and catch all "TD" elements, like this: 您可以尝试使用getElementsByTagName ，并捕获所有“ TD”元素，如下所示：
<html>
<body>
<script>
function _Change()
{
var TD = document.getElementsByTagName('td');
i=0;
do {
if ( TD[i].innerHTML.trim().localeCompare("three") == 0 ) TD[i].innerHTML = "3";
i++;
} while(i<TD.length)
}
</script>
<table border=1>
<tr><td> one </td> <td> two </td></tr>
<tr><td> three </td> <td> four </td></tr>
<tr><td> five </td> <td> six </td></tr>
</table>
<button onclick="_Change()"> change </button>
</body>
</html>
