.net 初学者。学习笔记 [html的select下拉标签option赋值]
前台：
<td> <asp:HiddenField ID="hidVehTypeId" runat="server" /> <asp:HiddenField ID="hidVehTypeName" runat="server" /> <select id="vehType1" name="vehType1"> </select></td>
后台(此方法须在页面加载是调用)：
/// <summary> /// 查询并把值赋予隐藏域 /// </summary> public void SelectVehType() { IList<RJ.Model.data_dictionary> dictionData = Business.UserInfo.SelectVehType(); string vehTypeId = ""; string vehTypeName = ""; foreach (var item in dictionData) { vehTypeId += "," + item.data_key; vehTypeName += "," + item.data_value; } this.hidVehTypeId.Value = vehTypeId.Substring(1); this.hidVehTypeName.Value = vehTypeName.Substring(1); }JS:
<script type="text/javascript"> function SelectVehType() { var typeid = $("#hidVehTypeId").val(); var typeidsil = typeid.split(","); var typename = $("#hidVehTypeName").val(); var typenamesil = typename.split(","); for (var i = 0; i < typeidsil.length; i++) { var sel = document.getElementById('vehType1'); var opt = document.createElement('option'); opt.setAttribute('value', typeidsil[i]); opt.innerText = typenamesil[i]; sel.appendChild(opt); } } </script>TAG:
