jQuery Removing specific text from an element

<div id="text">By: Anonymous From Minnesota</div>
I want it to just be:
我希望它只是：
<div id="text">Anonymous From Minnesota</div>

If you wanted to find every element with "By:" in it and remove it, you could try this:
如果你想找到每个带有“By：”的元素并将其删除，你可以试试这个：
$(':contains("By:")').each(function(){
$(this).html($(this).html().split("By:").join(""));
});
This removes any occurrence of "By:" in any element. If you want to target specfic type of elements, simply change $(':contains("By:")')to include whatever selector suits you.
这将删除任何元素中出现的任何“By：”。如果您想定位特定类型的元素，只需更改$(':contains("By:")')为包含适合您的任何选择器。

a more global solution using regular expressions. This will replace By:even if your string structure will change.
使用正则表达式的更全局的解决方案。By:即使您的字符串结构会改变，这也会替换。
var str = $('div').text().replace(/By:/g, '');
$('div').text(str);<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div id="text">By: Anonymous From Minnesota</div>回答by themerlinproject
var str = $("#text").text();
$("#text").text(str.substring(3));<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div id="text">By: Anonymous From Minnesota</div>Using javascript's substringand give your div an ID to access it easily:
使用 javascriptsubstring并为您的 div 提供一个 ID 以便轻松访问它：
html:
html：
<div id="text">By: Anonymous From Minnesota</div>
jquery:
查询：
var str = $("#text").text();
$("#text").text(str.substring(3));
You could do it in one line too:
你也可以在一行中完成：
$("#text").text($("#text").text().substring(3));
