我正在使用此选择样式脚本:http://www.bulgaria-web-developers.com/projects/javascript/selectbox/
有没有办法让新的选择器div宽度适应文本长度?目前它必须是css中定义的宽度。
droplist也一样吗?
我已经尝试过调整css,但我认为它可能只适用于jquery,但我不知道如何编辑文件以使其正常工作。
有什么想法吗?

这是一个适合您的实现。 http://jsfiddle.net/mq3g4/4/
$("#country_id").selectbox({
onOpen: function (inst) {
//there is no onCreated handler, so I have to use this.
//but if you want you can just fire this somewhere else
go();
//console.log("open", inst);
},
onClose: function (inst) {
//console.log("close", inst);
},
onChange: function (val, inst) {
console.log(val);
},
effect: "slide"
});
function go(){
var widestLI = 0;
//iterate through each LI and get the widest one
$(".sbOptions > li").each(function(){
var tmpWidth = $(this).textWidth();
if (tmpWidth > widestLI) widestLI = tmpWidth;
console.log(widestLI);
});
//now set both these elements to the widest width, plus 20px because of the padding
$(".sbOptions, .sbHolder").width(widestLI+20);
}
//from http://stackoverflow.com/questions/1582534/calculating-text-width-with-jquery
//this here gets the width of the html element.
$.fn.textWidth = function(){
var html_calc = $('<span>' + $(this).html() + '</span>');
html_calc.css('font-size',$(this).css('font-size')).hide();
html_calc.prependTo('body');
var width = html_calc.width();
html_calc.remove();
return width;
}
