Convert HTML-encoded < br/ > to html new line tag in jquery .text()
提问by user961627
I have some text in a variable sometextwhich I want to assign to divusing $('div').text(sometext);. The problem is that all <br/>s in sometextturn into < br/ >. I cannot use $('div').html()because there's a lot of internal structure that I want to retain within the div, so I can only use the .text()function.
我在一个变量中有一些文本sometext，我想分配给divusing $('div').text(sometext);。问题是所有的<br/>s 都sometext变成了< br/ >. 我无法使用，$('div').html()因为我想在 中保留很多内部结构div，所以我只能使用该.text()功能。
So once I've passed the text over the to the div, is there any way to change the encoded <br/>tag into a real line break in HTML? I mean something like this:
因此，一旦我将文本传递给div，有没有办法将编码的<br/>标签更改为HTML 中的真正换行符？我的意思是这样的：
$('div').convertMyBRsToHTML();

Your requested function should look like this:
您请求的函数应如下所示：
$.fn.convertMyBRsToHTML = function(text){
this.text(text);
this.html(this.html().replace(/<br\s*\/>/g,'<br/>'));
return this;
}
Now you could use by:
现在您可以通过以下方式使用：
$(YOUR_SELECTOR).convertMyBRsToHTML("<b>Some</b> new text.<br />next line<br />and so on");

You can replace the <br>s before setting the text:
您可以<br>在设置文本之前替换s：
$('div').text(sometext.replace(/<br\s*\/?>/gi, '\n');
