1JS $("#btn").click(function () { var imageEle = document.getElementById("images");//jquery 无法获取到 // 获取文件上传域内输入的多个文件 var fileList = imageEle.files; //遍历每个文件 for (var i = 0; i < fileList.length; i++) { var file = fileList[i]; // div
var dropDownList= document.getElementById("<%=DropDownListID.ClientID %>");//获取DropDownList控件 var dropDownListValue = dropDownList.options[dropDownList.selectedIndex].value;//获取选择项的值 //注:DropDownListID是DropDownList控件的ID. JS验证是否有非0值: -- if
