Having trouble with a calculation using a CSS property that is not returning any value.
Seems like the issue might be due to the CSS property returning '200px' instead of just '200'. Any suggestions for a workaround? Thanks in advance.
windowHeight = $(window).height(); // This is functioning
logoHeight = $('.home h1').css('height'); // Returns '200px'
logoPosition = windowHeight * 0.5 - logoHeight;
To ensure accurate calculations, it is crucial to convert the string "200px" to an integer by utilizing the parseInt method.
windowHeight = $(window).height(); // This operation works fine
logoHeight = parseInt($('.home h1').css('height'), 10); // However, this results in '200px'
logoPosition = windowHeight * 0.5 - logoHeight;
If you fail to convert the string properly, your calculation of windowHeight * 0.5 - logoHeight will yield NaN (not a number).
It's essential to provide the radix as the second argument when using parseInt, or else unexpected results may occur. For example;
parseInt("022") == 18; // This evaluates to true
To retrieve the height of the <h1> element, you can simply use the height() method:
winHeight = $(window).height(); // Easily obtain window height
elementHeight = $('.header h1').height();
elementPosition = winHeight * 0.5 - elementHeight;
Check out this example:
windowHeight = $(window).height(); // Fetch the window height
logoHeight = $('.home h1').css('height'); // Get the height of 'h1' element under '.home'
logoPosition = windowHeight * 0.5 - parseInt(logoHeight); // Calculate the logo's position
