jQuery:将TextArea内容转换为html字符串,反之亦然 [英] jQuery: Convert TextArea content to html string and vice versa
问题描述
你喜欢jQuery吗?
你喜欢jQuery吗?
$
您必须将结果字符串放入''元素中:
Hi folks!< br>你喜欢jQuery吗?< br>我做到了!
这是因为TextArea内的换行符必须转换为< br> ;
tag!
如果您想将元素的html放入TextArea输入字段中,例如:
Hi folks!< br>你喜欢jQuery吗?< br>我做的!
应该转换为:
伙计们!
您喜欢jQuery吗?
我做!
那么,有没有办法将字符串转换为html-string(反之亦然),还是应该自己写一个函数?

使用适当的元素样式,您不需要转换任何东西。使用设置为 pre 的CSS white-space 属性,元素中的任何空格应该与textarea中的空格完全相同:
#myElement {white-space:pre; }

what I'm trying to do is converting a TextArea content into a valid html code. Suppose you type inside the TextArea and then you press a button that shows the typed text inside a element. If you typed something like inside the TextArea:
Hi folks!
Do you like jQuery?
I do!
The resulting string you have to put inside the '' element is:
Hi folks!<br>Do you like jQuery?<br>I do!
That's because the newline inside the TextArea must be converted to the <br>
tag!
The same thing should happend if you want to take the html of the element and put it inside the TextArea input field, for example:
Hi folks!<br>Do you like jQuery?<br>I do!
should be converted to:
Hi folks!
Do you like jQuery?
I do!
So, is there a way to convert a string to html-string (and vice versa) or should I write a function by myself?
Thanks in advance!
With the appropriate styling on the element, you shouldn't need to convert anything. Using the CSS white-space property with a value set to pre, any white-space in the element should appear exactly as it does in the textarea:
#myElement { white-space: pre; }
