[英]Javascript stripping out substring and appending it
I am trying to do something which should be simple but I'm having no luck.我正在尝试做一些应该很简单但我没有运气的事情。 I have a string like the following:
我有一个如下字符串:
<hgc attr="something">late at</hgc>
and I need to strip out the last at
prior to the closing html tag and append it, surrounded by its own tag to produce:我需要
at
关闭 html 标签和 append 之前去掉最后一个,由它自己的标签包围以产生:
<hgc attr="something">late </hgc><hgb>at</hgb>
Don't worry about the tags, they are custom.不用担心标签,它们是自定义的。
Update更新
That at
word may be anything, even hgc
and I will already have the word ahead of time to produce the appended html. at
字可能是任何东西,即使是hgc
和我也已经提前得到了这个字来生成附加的 html。
I have attempted to perform the following:我试图执行以下操作:
let markup = '<hgb>' + word + '</hgb>';
let applied = $element.html().slice(0, pos) +
$element.html().slice(pos).replace(word, "") +
markup;
Try this one.试试这个。
let str = '<hgc attr="something">late at</hgc>'; let reg = /\w+(?=<)/g; let word = str.match(reg)[0]; str = `${str.split(reg).join('')}<hgb>${word}</hgb>`; console.log(str);
Something like this should work.像这样的东西应该工作。
