[英]regex replace element text
Never seem to master those regex's... 似乎从未掌握过这些正则表达式的...
I need to update the total with newVal 我需要用newVal更新总数
<span class="myClass">some text Total (12)</span>
into 进入
<span class="myClass">some text Total (13)</span>
and also without a current value 也没有当前值
<span class="myClass">some text Total</span>
into 进入
<span class="myClass">some text Total (13)</span>
oh, and some text can be anything 哦,有些文字可以是任何东西
my code 我的密码
newVal = 13;
$('.myClass').text( $('.myClass').text().replace(???, ???) );
You could wrap counters with span
: 您可以使用span
包裹计数器:
<span class="myClass">some text Total (<span>12</span>)</span>
and do like so: 并这样做:
newVal = 13;
$('.myClass span').text(newVal);
Wrong approach, your code would only return the new string. 错误的方法,您的代码将仅返回新字符串。 To set it, use 要设置它,使用
$('.myClass').text(function(i, old){
return old.replace(/(\s+\(\d+\))?$/, " ("+newVal+")");
})
The regex matches the string end, and (optionally) whitespaces + bracketed number before. 正则表达式匹配字符串结尾,并且(可选)匹配空格+之前的括号。
