用js獲取select的多個(gè)選項(xiàng)值?
以下兩種使用js獲取select的方法如下:VAR obj=document.getElementByIdxX(“testselect”)來定位idvar索引=對(duì)象選擇索引選擇索引變量文本=對(duì)象選項(xiàng)[索引]。text選擇文本變量值=對(duì)象選項(xiàng)[索引]。Value在jQuery中獲取所選select值的第一種方法是$(“#testselect)選項(xiàng):選中"). Text()所選文本$(“#testselect)選項(xiàng):選中"). Val()選定值$(“#testselect”)。獲取(0)。selectedindex索引的第二種方式是$(“#tesetselect”)。查找(“選項(xiàng):選中"). Text()//選定的Text.val()。獲?。?)。Selectedindex
怎么在js中獲得select標(biāo)簽被選中的值?
JS控制項(xiàng)的選擇。代碼如下:<html><script type=“text/JavaScript”> var selectedvalue=“<%=請求.getAttribute(“l(fā)ine”)%>“函數(shù)changeSelected(){jsSelectItemByValue(文檔.getElementById(“mySelect”,selectedValue)}函數(shù)jsSelectItemByValue(objSelect,objItemText){for(var i=0i<objSelect.options.lengthi文件){如果(objSelect.options選項(xiàng)[i] .value==objItemText){objSelect.options選項(xiàng)[i] .selected=true break}}}</script><body onload=“changeSelected()”><select Id=“myselect”name=“myselect”>< option value=“0”>0</option>< option value=“1”>1</option>< option value=“2”>2</option>< option value=“3”</option></Select></body></HTML>

獲取所選文本:

~]$(“選擇選項(xiàng):選中).attr(“id”)<select><option value=“12”id=“56”>89</option><option value=“23”id=“45”>78</option><option value=“34”id=“34”>67</option></select>
