in my example http://jsfiddle.net/radek/HnXC4/2/ I defined jQuery handler for click
via $(":button, .run").click(function(){
how come the this button should NOT work
button's clicked is fired too? It doesn't have class "run".
Try:
$(":button.run").click(function(){
$(":button, .run")
will match any elements that are either buttons or have a CSS class of run
.
You don't need the comma in between:
$(":button.run").click(function(){};
What you want is:
$(":button.run").click(function(){});
This means "all buttons that ALSO have the class 'run'". When you include a comma in the selectors, it means "all elements that are buttons, as well as all elements that have class 'run'", as you had here:
$(":button, .run").click(function(){});
For completeness, if you have a space in the selector without the comma, such as:
$(":button .run").click(function(){});
That means all elements with class 'run' that are descendents of buttons. Not sure buttons can have descendents, but you get the idea.
