在textarea中添加行 [英] add line in textarea

问题描述

我有一个textarea。单击按钮将值插入textarea

I have a textarea. the value is inserted in the textarea on the click of a button

function addText(elId,text) {
	if(document.getElementById("NewJudge").value != "")
	{
	var text_area_id = document.getElementById("hc_judge");
    var judge_name =(document.getElementById("NewJudge").value + "  , ") ;
    var txt = document.createTextNode(judge_name);
    text_area_id.appendChild(txt);
    document.getElementById("NewJudge").value ="";
	}
}

我使用'，'来分隔textarea中的值。但是新的价值应该是一个新的界限。

我在网上搜索并发现'& ＃13; &安培; ＃10;'用于在textarea中添加新行。但是当我使用这段代码时

I used ',' to seperate values in the textarea. but the new values should be in a new line.
I searched the net and found that '& #13; & #10;' is used to add new line in textarea. But when I use this code

<pre lang="Javascript">
function addText(elId,text) {
    if(document.getElementById("NewJudge").value != "")
    {
    var text_area_id = document.getElementById("hc_judge");
    var judge_name =(document.getElementById("NewJudge").value + "  & #13;& #10; ") ;
    var txt = document.createTextNode(judge_name);
    text_area_id.appendChild(txt);
    document.getElementById("NewJudge").value ="";
    }
}
</pre>

。

它保持文本不变。

i故意在&之间放置空格＃因为它在这里创建了一个新行：D

但是当在代码中使用时它不起作用。请帮忙。在此先感谢：）

.
it keeps the text as it is.
i purposely put space between & # as it creates a new line here too :D
but when used in code it isnt working. Please help. Thanks in advance :)

推荐答案

你可以使用'\ n'作为换行符。



var judge_name =（document.getElementById（NewJudge）。value +'\ n'）;

you can use '\n ' as new line character.

var judge_name =(document.getElementById("NewJudge").value + '\n ') ;
