Padding in select boxes

阅读更多关于 Padding in select boxes

I know select boxes are a bit of a pain to style with css, but without resorting to advanced techniques is there anyway I can add some padding to push down the text a bit without it also adding padding to the arrow on the right hand side? add this to your CSS class. Maybe this helps? -webkit-appearance:none; -moz-appearance:none; appearance:none; Since select boxes appear differently on different browsers and especially operating systems, you cannot guarantee a consistency. For example, the minimal amount of formatting I can do on a mac is this: select { height:40px; background:transparent; }

With Mootools, if I attach a change event listener on a <select> how do I access the option that was selected. I would like the actual element and not just the value. $('select').addEvent('change',function(event) { //?? }); Either of these will work: find by :selected pseudo selector in descendants this.getElement(':selected'); get first selected value this.getSelected()[0]; pure javascript, use the selectedIndex property this.options[this.selectedIndex]; Just access the selectedIndex property on the select element ( this object in the event handler) to get the option index. // get the index

阅读更多关于 HTML select element type is 'select-one' when jQuery is included. Is it a cross browser value?

When I alerted the type of a select element in JavaScript it displayed 'select-one'.

Dynamically truncate <option> text to fit <select> list

阅读更多关于 Dynamically truncate text to fit list

By default, the selector list shown for a <select></select> element will be as wide as the widest <option></option> child it contains. If I hardcode the width of the select tag with CSS to make it more narrow, the widest option is truncated in the display. I want to trim down the option text to fit the selection list, appending ... (ellipsis) to show that it's truncated when the option is selected, however, when I expand the dropdown I want the text in the dropdown to be full width, without trailing ellipsis. How would I accomplish that? Using css and jQuery : select, option.selected { width

阅读更多关于 Why is the dropdown box of SELECT tag shown at wrong place?

My CSS file doesn't touch the tag 'select' at all, also no CSS classes are related to the tag 'select'.
