Javascript RegExp match text between <a> tags
提问by Ovidiu Aleka
I need to match with a javascript RegExp the string: bimbo999 from this a tag: <a href="/game.php?village=828&screen=info_player&id=29956" >bimbo999</a>
我需要用一个 javascript RegExp 匹配字符串：bimbo999 来自这个标签： <a href="/game.php?village=828&screen=info_player&id=29956" >bimbo999</a>
The numbers from URL vars (village and id) are changing every time so I have to match the numbers somehow with RegExp.
来自 URL 变量（村庄和 id）的数字每次都在变化，所以我必须以某种方式将数字与 RegExp 匹配。

Try this:
尝试这个：
/<a[^>]*>([\s\S]*?)<\/a>/
<a[^>]*>matches the openingatag([\s\S]*?)matches any characters before the closing tag, as few as possible<\/a>matches the closing tag
<a[^>]*>匹配开始a标签([\s\S]*?)匹配结束标记之前的任何字符，尽可能少<\/a>匹配结束标签
The ([\s\S]*?)captures the text between the tags as argument 1 in the array returned from an execor matchcall.
所述([\s\S]*?)捕获作为在阵列中的参数1的标签之间的文本从返回exec或match呼叫。
This is really only good for findingtext within aelements, it's not incredibly safe or reliable, but if you've got a big page of links and you just need their text, this will do it.
这真的只适用于在元素中查找文本a，它不是非常安全或可靠，但是如果您有一大页链接并且您只需要它们的文本，那么就可以了。
A much safer way to do this without RegExp would be:
没有 RegExp 的更安全的方法是：
function getAnchorTexts(htmlStr) {
var div,
anchors,
i,
texts;
div = document.createElement('div');
div.innerHTML = htmlStr;
anchors = div.getElementsByTagName('a');
texts = [];
for (i = 0; i < anchors.length; i += 1) {
texts.push(anchors[i].text);
}
return texts;
}

I don't have experience with Regex, but I think you can use JQuery with .text()!
我没有使用 Regex 的经验，但我认为您可以将 JQuery 与.text()!
I mean if you use :
我的意思是如果你使用：
var hrefText = $("a").text();
You will get your text without using Regex!
您无需使用正则表达式即可获得文本！
.find("a")and then gives you a list of a's tags objects and then use .each()to loop on that list then you can get the text by using .text().
.find("a")然后为您提供a的标签对象列表，然后用于.each()在该列表上循环，然后您可以使用.text().
Or your can use a class selector, id or anything you want!
或者您可以使用类选择器、id 或任何您想要的东西！
