如何在textarea输入中去除html标签 [英] how do you strip html tags in textarea input
问题描述
我已经设置了一个小的web应用程序,您在其中添加post-it到页面。这只是一个项目,以帮助更好地学习JavaScript / jQuery,它似乎是一个适当的项目(我是新的JS / jQuery)。
这是小提琴: a href =http://jsfiddle.net/mitchbregs/mWaPz/> http://jsfiddle.net/mitchbregs/mWaPz/
我发现此网站: http://www.hscripts.com/scripts/JavaScript/remove-html- tag.php
我实现的代码如下:
function stripHTML(){
var re = /(<([^>] +)>)/ gi;
for(i = 0; i< arguments.length; i ++)
arguments [i] .value = arguments [i] .value.replace(re,)
}
它仍无法工作。
问题:我需要它,以便当有人向textarea中输入文本时,如果他们输入这样的< b> Hi< / b>
,它会从输入中剥离< b>
标签,只留下文本。
您有三个问题:一个是方法没有正确返回(这是谁写的错的)。接下来是你在 $(document).ready()
中定义方法,因此无法找到(至少在Chrome中)。第三,你不是以正确的方式调用它( onSubmit
将永远不会在这里使用)。
使用@ Joao的方法(所以你应该upvote他的答案),并使用这种方法,移出 ready()
函数:
function stripHTML(str){
var strippedText = $(< div />)。html(str).text
return strippedText;
}
也称为:
var post = stripHTML($(。text_input)。val())

I have set up a little web application where you add post-its to a page. It's just a project to help better learn JavaScript/jQuery and it seemed like an appropriate project (I'm new to JS/jQuery).
This is the fiddle: http://jsfiddle.net/mitchbregs/mWaPz/
I found this website: http://www.hscripts.com/scripts/JavaScript/remove-html-tag.php
I implemented the code as so:
function stripHTML(){ var re = /(<([^>]+)>)/gi; for (i=0; i < arguments.length; i++) arguments[i].value=arguments[i].value.replace(re, "") }
and it still didnt work.
The problem: I need it so that when somebody inputs text into the textarea, if they input something like this "
<b>Hi</b>
" it would strip the "<b>
" tag from the input and leave just the text.If someone could help me out this it would be great.. Thanks!
解决方案You have three issues: One is that the method is not returning properly (that's the fault of whoever wrote it). Next is that you are defining the method within
$(document).ready()
, so it is not able to be found (at least in Chrome). Third, you are not calling it the right way (onSubmit
will never be used here).I've used @Joao's method (so you should upvote his answer) and used this method, moved outside of the
ready()
function:function stripHTML(str){ var strippedText = $("<div/>").html(str).text(); return strippedText; }
And also called it here:
var post = stripHTML($(".text_input").val())
