JavaScript用空格替换下划线 [英] Javascript replace underscore with space
问题描述
我有一个数组,其中包含对象,其中一些对象在字符串中包含下划线
I have an array with objects inside of it, a few of the objects contain an underscore in the string
示例
{"name": "My_name"}
但是我要在多个地方调用name函数,一个这样的地方是在图像标签中必须使用下划线的地方,使用javascript或jquery我想选择一个带有其名称的div并用下划线替换一个空格
but i'm calling the name function in multiple places, one such place is in an image tag where the underscore is necessary, using javascript or jquery i want to select a certain div with the name in it and replace the underscore with a space
示例
<div>
<div class="name">
My_name
</div>
<img src="My_name.jpg"/>
</div>
在div.name中,我要说的是我的名字,而不是My_name
In the div.name I want it to say My name instead of My_name

I'm currently using jQuery, and jQuery UI for my project
推荐答案
您可以将字符串中的所有下划线替换为如下空格:
You can replace all underscores in a string with a space like so:
str.replace(/_/g, ' ');
因此,只需在放入内容之前执行此操作.如果之后需要执行替换,请使用each
循环:
So just do that before the content is put in. If you need to perform the replacement afterwards, loop using each
:
$('.name').each(function() {
var $this = $(this);
$this.text($this.text().replace(/_/g, ' '));
});
