These are the strings I have:
"test123.00" "yes50.00" I want to add the 123.00 with 50.00.
How can I do this?
I used the command parseInt() but it displays NaN error in alert box.
This is the code:
str1 = "test123.00"; str2 = "yes50.00"; total = parseInt(str1)+parseInt(str2); alert(total); 
251
Find code to convert String to Integer using jQuery. To convert, use JavaScript parseInt() function which parses a string and returns an integer. var sVal = '234'; var iNum = parseInt(sVal); //Output will be 234.
In JavaScript parseInt() function (or a method) is used to convert the passed in string parameter or value to an integer value itself. This function returns an integer of base which is specified in second argument of parseInt() function.
repeat() is an inbuilt function in JavaScript which is used to build a new string containing a specified number of copies of the string on which this function has been called. Syntax: string. repeat(count);
Answer: Use the jQuery. isNumeric() method You can use the jQuery $. isNumeric() method to check whether a value is numeric or a number. The $. isNumeric() returns true only if the argument is of type number, or if it's of type string and it can be coerced into finite numbers, otherwise it returns false .
just do this , you need to remove char other than "numeric" and "." form your string will do work for you
yourString = yourString.replace ( /[^\d.]/g, '' ); your final code will be
str1 = "test123.00".replace ( /[^\d.]/g, '' ); str2 = "yes50.00".replace ( /[^\d.]/g, '' ); total = parseInt(str1, 10) + parseInt(str2, 10); alert(total); For parseInt to work, your string should have only numerical data. Something like this:
str1 = "123.00"; str2 = "50.00"; total = parseInt(str1)+parseInt(str2); alert(total); Can you split the string before you start processing them for a total?
