今天你学习了吗？本篇实例上传图片，需要注意的是ID名称不要出现重复，否则运行时会被误导，增加自己的调试bug时间。<form  enctype="multipart/form-data" id="fm4"  method="post" novalidate minimizable >  <input type="file" name="upload" id="upload1"  class="easyui-validatebox" validType="fileType['BMP|GIF|JPG|JPEG|ICO|PNG|TIF']"  invalidMessage="请选择(BMP|GIF|JPG|JPEG|ICO|PNG|TIF)等格式的图片"/>      <a href="javascript:void(0)" id="category_image3"  class="easyui-linkbutton my-dialog-button" type="submit" plain="true" icon="icon-ok" onclick="saveuser3()" iconcls="icon-save">上传</a></form>

//上传图片function saveuser3(){var nameValue1=window.document.getElementById("category_image3").value; //alert(nameValue1);if (nameValue1 == ""){window.alert("上传失败! 请重新选择图片");return false;}   else{if(/\.(gif|jpg|jpeg|png|GIF|JPG|PNG)$/.test(nameValue1)){alert("图片类型必须是.gif,jpeg,jpg,png中的一种")return false;}}$("#fm4").form("submit", { url: '{:U('Inter/admin/general_upload')}',  success: function (result) {  if (result) {
