在input上设置onkeyup事件,输入文字时触发
function searchItem(e,myselectid){ var keywords = $(e).val(); keywords=keywords.replace(/ /g,"") //去掉空格 var myselect=$("#"+myselectid)[0]; //得到select对象 if(keywords!=""){ for(i=0;i<myselect.length;i++)// 循环option { if(myselect.options[i].text.indexOf(keywords)!=-1) //判断option的text是否包含keyword { $option = $(myselect.options[i]); $(myselect.options[i]).remove(); $(myselect).prepend($option); } } } //alert(myselect.options.length); }
