specialEasing in animate

[Axdr]

If you're trying to animate font size using special per-property easing it won't work. For example:

$("span").animate({font-size:'2em'}, {duration: 1000, specialEasing: {'font-size': 'special'}});

A conflict is between

• - 5328 var name = p.replace(rdashAlpha, fcamelCase);

and

• - 5618 var specialEasing = this.options.specialEasing && this.options.specialEasing[this.prop];

this.prop will be 'fontSize' instead of 'font-size' but 'fontSize' is not a CSS name. This will work:

$("span").animate({font-size:'2em'}, {duration: 1000, specialEasing: {'fontSize': 'special'}});

Sorry for my awful english.

sorry $("span").animate({font-size:'2em'}, {duration: 1000, specialEasing: {'fontSize': 'special'}}); this won't work also

I use this:

• 5618

    var altName = this.prop.replace(
  	    /([a-z])([A-Z])/g, 
  	    function(s,b1,b2){return b1 + "-" + b2.toLowerCase()}
  	);
  	var specialEasing = 
            this.options.specialEasing && 
              (this.options.specialEasing[this.prop] ||  
               this.options.specialEasing[altName]
  	    );

This is better solution.

• line 5330

      if ( p !== name ) {
          prop[ name ] = prop[ p ];
          delete prop[ p ]; 
          p = name;
      }
  

must be changed

    if ( p !== name ) {
        if (opt.specialEasing && opt.specialEasing[p]) {
            opt.specialEasing[name] = opt.specialEasing[p];
            delete opt.specialEasing[p];
        }
        prop[ name ] = prop[ p ];
        delete prop[ p ]; 
        p = name;
    }

The line 5618 rests unaffected.

Thanks for taking the time to contribute to the jQuery project by writing a bug report and providing a testcase!

Your test case contained a syntax error and there is no easing called "special". After fixing these in your test code I uploaded a reconstructed version of your test case here ​test case.

This works just fine for me with no errors and the text animated.

If you feel this ticket was incorrectly closed or the bug still persists for you, feel free to report back with a reproducible test case and reopen the issue.
