When i write a jQuery plugin i like to specify options for spacings the CSS way.
I wrote a function that returns a CSS String as values in a object.
5px 10px returns top: 5px, right: 10px, bottom: 5px, left: 10px
Now i often use the returned values to do some calculations and its not very nice to have to extract the measuring unit every time...
I suck in writing regular expressions could someone help me complete this function:
this.cssMeasure = function(cssString, separateUnits){
if ( cssString ){
var values = {}
}else{
return errorMsg
}
var spacing = cssString.split(' ')
var errorMsg = 'please format your css values correctly dude'
if( spacing[4] || (spacing[2] && !spacing[3]) ) {
return errorMsg
} else if ( spacing[3] ) {
values = {top: spacing[0], right:spacing[1], bottom:spacing[2], left:spacing[3]}
} else if ( spacing[1] ) {
values = {top: spacing[0], right:spacing[1], bottom:spacing[0], left:spacing[1]}
} else {
values = {top: spacing[0], right:spacing[0], bottom:spacing[0], left:spacing[0]}
}
if (separateUnits) {
$.each(values, function(i, value){
/*
at this place i need to extract the measuring unit of each value and return them separately
something like top: {value: 10, unit: 'px'}, right: {bla} and so on
*/
})
}
return values
}
if you have any idea how to improve this function i am open to your comments.
