jQuery method to replace line breaks in textarea_jquery

The example in this article describes how jQuery replaces line breaks in textarea. Share it with everyone for your reference. The specific analysis is as follows:

When my colleague was learning jQuery yesterday, he wanted to replace the line breaks in the textarea.

html part:

<fieldset>
 <textarea id="ncontent"></textarea>
</fieldset>
<button id="submit">提  交</button> 

js part:

$(document).ready(function(){ 
  $("#submit").click(function(){ 
    var ss = $("#ncontent").text(); 
    alert(ss); 
    var str = ss.replace(//r/n/gi, "!!!"); 
    alert(str); 
  }); 
}); 
</script>

After using JavaScript’s replace() method, the newline is still not replaced.

The problem is that jQuery gets the value in textarea. Should use

Copy code The code is as follows:

var ss = $("#ncontent").html();

Using the text() or val() method will process the html tags in the textarea, so /r/n will definitely not be replaced.

I hope this article will be helpful to everyone’s jQuery programming.
