Remove last line from string

javascript, jquery

Solution

Try:

if(x.lastIndexOf("\n")>0) {
    return x.substring(0, x.lastIndexOf("\n"));
} else {
    return x;
}

Problem

How do I remove the last line "\n" from a string, if I dont know how big the string will be? ``` var tempHTML = content.document.body.innerHTML; var HTMLWithoutLastLine = RemoveLastLine(tempHTML); function RemoveLastLine(tempHTML) { // code } ```
