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);
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);
-? E.g. -123.00For 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?
str1 = "test123.00";
str2 = "yes50.00";
intStr1 = str1.replace(/[A-Za-z$-]/g, "");
intStr2 = str2.replace(/[A-Za-z$-]/g, "");
total = parseInt(intStr1)+parseInt(intStr2);
alert(total);
working Jsfiddle
Is this logically possible??.. I guess the approach that you must take is this way :
Str1 ="test123.00"
Str2 ="yes50.00"
This will be impossible to tackle unless you have delimiter in between test and 123.00
eg: Str1 = "test-123.00"
Then you can split this way
Str2 = Str1.split("-");
This will return you an array of words split with "-"
Then you can do parseFloat(Str2[1]) to get the floating value i.e 123.00
