How Can I Change An Html Input Value's Data Type To Integer?

I'm using jQuery to retrieve a value submitted by an input button. The value is supposed to be an integer. I want to increment it by one and display it. // Getting immediate Voting

Solution 1:

To convert strValue into an integer, either use:

parseInt(strValue, 10);

or the unary + operator.

+strValue

Note the radix parameter to parseInt because a leading 0 would cause parseInt to assume that the input was in octal, and an input of 010 would give the value of 8 instead of 10

Solution 2:

parseInt(  $("#"+countUp).val()  ,  10  )

Solution 3:

Use parseInt as in: var count = parseInt($("#"+countUp).val(), 10) + 1; or the + operator as in var count = +$("#"+countUp).val() + 1;

Solution 4:

There is a parseInt method for that or Number constructor.

Solution 5:

var count = parseInt(countUp, 10) + 1;

See w3schools webpage for parseInt.
