I have a function that has a values inserted into variables in another function.
Initialise:
When the window resizes, it fires the resizeImage() function.
$(window).resize(function () {
resizeImage();
});
Resize Function:
This function checks every element with the image-resize class and add readjust the SRC for the image by changing the width value (dynamic from scene7).
The problem is that element.attr('src', newSrc); newSrc doesn't exist as its stored in sizingMethod().
Is there anyway of grabbing the variable from sizingMethod() function and placing it within the element.attr('src', newSrc);.
function resizeImage() {
$('.image-resize').each(function () {
var element = $(this), src = $(this).attr('src'), regx = /wid=\d+(\.\d)*/g, currentWidth, newWidth, newSrc;
var attrElement = $(this), attrSrc = $(this).attr('data-zoom-image'), attrRegex = /wid=\d+(\.\d)*/g, attrCurrentWidth, attrNewWidth, attrNewSrc;
if ($(window).width() > 1824) {
sizingMethod(src, regx, currentWidth, newWidth, newSrc, '2000');
} else if ($(window).width() <= 1824 && $(window).width() > 1366) {
sizingMethod(src, regx, currentWidth, newWidth, newSrc, '1824');
}
element.attr('src', newSrc);
});
};
Sizing Function:
function sizingMethod(sSrc, sRegex, sCurrentW, sNewW, sNewSrc, sNewWidth){
sCurrentW = sSrc.match(sRegex);
sNewW = 'wid=' + sNewWidth;
sNewSrc = sSrc.replace(sCurrentW, sNewW);
textWidth = sNewW.replace('wid=', '');
$(".dsply-screen-size").text($(window).width());
$(".dsply-image-size").text(textWidth);
}
When you use a primitive, what you send is the value not the reference, so the sNewSrc != newSrc, so any changes you do to sNewSrc that variable will not change newSrc.
You can fix your code using:
return: returning the value in the function sizingMethod:
Sizing Function:
closure: if declare sizingMethod inside the anonymous function you have access to the variable newSrc and other variables as well.
object: if you use an object/array instead of a primitive as an argument
Sizing Function:
