删除字符串中的空格，特殊字符并将其转换为小写

Question

I need to format a string for comparison purpose. Lets say we have Multiple Choice I want to convert it to multiplechoice So white spaces removed, any special characters removed and lowercase.

I need to do this in SAPUI5 while comparing a value which I get from a model.

if (oCurrentQuestionModel.getProperty("/type") === "multiple choice")

How can I achieve this?

Answer 1

You can do it as:

var str = "Multiple Choice";
var strLower = str.toLowerCase();

strLower.replace(/\s/g, '');

Working demo .

The Regex

\\s is the regex for "whitespace", and g is the "global" flag, meaning match all \\s (whitespaces).

Answer 2

function cleaner(str) {

    if (str) {

        var strLower = str.toLowerCase();
        return strLower.replace(/\W/g, '');

    }

    return false;

}
