What is the method for concatenating two strings in JavaScript without any whitespace in between?

When working with two strings involving time, consider the following scenario:

var gettime= $("#select-choice-2 :selected").text();

The above code returns a time value in 24-hour format, such as

17:45

However, if you require the time to display in the format

17:45:00.000

You can utilize an additional string like this:

var ext=':00.000';

To concatenate these two strings properly and obtain the desired result.

If you encounter issues where "gettime" is not displaying as expected and appears to not be a proper string, one solution is to convert it explicitly into a string before further manipulation. You may do so by using appropriate methods or functions provided by JavaScript.

In some cases, the variable scope can lead to unexpected behavior, as seen when "gettime" did not appear in the alert box due to being a local variable while "ext" was used within another function. This kind of oversight can cause confusion but can be resolved by ensuring variables are accessible where they are needed.

Answer №1

To combine two strings, you can simply use the concatenation operator:

alert( getTime + extension );

Answer №2

Are you looking to simply concatenate the strings? If so, you can achieve that using the following code snippet:

var combinedStrings = firstString + secondString;

Answer №3

When attempting to join strings together in certain browsers, using the + operator may result in unexpected line breaks within the resulting string. To ensure proper concatenation, you should use the following standard method:

getTime.concat(ext)

Answer №4

**
I understand the issue with scope now. The issue was that `gettime` was declared as a local variable within one function, and `ext` was accessed in a different function. That's why `gettime` is not showing up in the alert box of the function. **
