Question

I have this string:

var s = '<span style="font-size:13px">20<div class="lblTitle"></div><span>';    

I’d like to replace the 20 to 40, I tried:

a.replace(/>(\d*)</, 40)  

But it will result in:

<span style="font-size:13px"40div class="lblTitle"></div></span>  

the > and < are replaced too…
What should I do?

Answer 1

You could match the > and < and then put them next to the replacement:

.replace(/(>)\d*(<)/, "$140$2")

or simply use:

.replace(/>(\d*)</, ">40<")

You are replacing this in string, so you don’t need the replacement to be an integer.
