[英]Replace STYLE content javascript HTML
I have a JavaScript variable: 我有一个JavaScript变量:
var s =
"<html><head><style>body{a:b;c:d}</style></head><body></body></html>";
First, I am extracting the content inside <style>
tags: 首先,我提取
<style>
标记内的内容:
s = s.split(/(<style[^>]*>|<\/style>)/i)[2];
// s == "body{a:b;c:d}";
Then I am doing something with s
and after the manipulation I need to append it on <style>
tags. 然后我用
s
做一些操作,在操作之后,我需要将其附加到<style>
标记上。
How can I insert s
between <style>
and </style>
? 我怎样才能插入
s
之间<style>
和</style>
?
Example: Modified var s = "body{x:h;f:l;}"; 示例:修改后的var s =“ body {x:h; f:l;}”;
so I need the resulting content like this: 所以我需要这样的结果内容:
"<html><head><style>body{x:h;f:l;}</style></head><body></body></html>";
Update : jQuery is allowed - But only string manipulation is allowed. 更新 :允许使用jQuery-但仅允许字符串操作。 Pure JavaScript solutions have first priority.
纯JavaScript解决方案具有最高优先级。
var s = "<html><head><style>body{a:b;c:d}</style></head><body></body></html>";
var b = s.split(/(<style[^>]*>|<\/style>)/i)[2];
s = s.replace(b,"body{x:h;f:l;}");
finally, s is what you want. 最后,s是您想要的。
Does this work for you: 这对您有用吗:
var s ="body{a:b;c:d}"; var newS = s.replace("body{a:b;c:d}", "body{x:h;f:l;}"); alert(s); alert(newS);
Use below mentioned code 使用下面提到的代码
var someHTML = "<html><head><style>body{a:b;c:d}</style></head><body></body></html>";
var styleContents = someHTML.split(/(<style[^>]*>|<\/style>)/i)[2];
document.getElementById('style').innerHTML = styleContents;
