Javascript .replace() not working

Question

carList = cars.innerHTML;
alert(carList);
carList = carList.replace(\"\",\"\").replace(\"\",\"\").replace(\"\",\"\").replace(\"         


        

Answer 1

Using .replace() with a string will only fix the first occurrence which is what you are seeing. If you do it with a regular expression instead you can specify that it should be global (by specifying it with a g afterwards) and thus take all occurrences.

carList = "<center>blabla</center> <b>some bold stuff</b> <b>some other bold stuff</b>";
alert(carList);
carList = carList.replace(/<center>/g,"").replace(/<\/center>/g,"").replace(/<b>/g,"").replace(/<\/b>/g,"");
alert(carList);

See this fiddle for a working sample.

Answer 2

You can use a regular expression to match all of these at the same time:

carList = carList.replace(/<\/?(b|center)>/g,"");

The g flag at the end of the match string tells Javascript to replace all occurrences, not just the first one.
