jqgrid上要显示图片和上传图片的列,格式如下:
{label:'图片',name:'icon',index:'icon',autowidth:true,formatter:alarmFormatter,editable:true,edittype:'custom',editoptions:{custom_element: ImgUpload,custom_value:GetImgValue}},
注意:edittype要为custom 也就是自定义编辑格式.
editoptions:{custom_element: ImgUpload,custom_value:GetImgValue}}
- 在
jqgrid的列表里显示图片用到的js function此处与图片的上传没关系.
function alarmFormatter(cellvalue,options,rowdata){
return '<img src="__MODULE__/download/download?id= '+ rowdata.icon + '" style="width:50x;height:50px" />'
}
- 下面为上传用到的 js 文件
upload.js
/**
4. 自定义文件上传列
5. @param value
6. @param editOptions
7. @returns {*|jQuery|HTMLElement}
8. @constructor
*/
function ImgUpload(value,editOptions) {
var span = $("<span>");
var hiddenValue = $("<input>",{type:"hidden",val:value,name:"fileName",id:"fileName"});
var image = $("<img>",{name:"uploadImage",id:"uploadImage",value:'',style:"display:none;width:80px;height:80px"});
var el = document.createElement("input");
el.type = "file";
el.id = "imgFile";
el.name = "imgFile";
el.onchange = UploadFile;
span.append(el).append(hiddenValue).append(image);
return span;
}
/**
9. 调用 ajaxFileUpload 上传文件
10. @returns {boolean}
11. @constructor
*/
function UploadFile() {
$.ajaxFileUpload({
url : 'index.php/Home/upload/upload',type : 'POST',secureuri:false,fileElementId: 'imgFile',dataType : 'json',success: function(data,status){
//显示图片
$("#fileName").val(data.id);
$("#uploadImage").attr("src","index.php/Home/download/download?id=" + data.id);
$("#uploadImage").show();
$("#imgFile").hide()
},error: function(data,status,e){
alert(e);
}
});
return false;
}
/**
12. icon 编辑的时候该列对应的实际值
13. @param elem
14. @param sg
15. @param value
16. @returns {*|jQuery}
17. @constructor
*/
function GetImgValue(elem,sg,value){
return $(elem).find("#fileName").val();
}
- 下面为
ThinkPHP上传代码部分
<?php
/**

* Time: 14:16
*/
namespace Home\Controller;
use Home\Common\HomeController;
use Think\Upload;
class UploadController extends HomeController
{
public function upload(){
$upload = new Upload();
$upload->maxSize = 4194304; //4MB
$upload->exts = array('jpg','gif','png','jpeg');
$upload->rootPath = C("FILE_PATH"); //根目录
$upload->autoSub = false;
// $upload->savePath = C("FILE_PATH"); //附件上传目录,相对于根目录
// $upload->saveName = array('uniqid','');
//上传文件
$info = $upload->uploadOne($_FILES['imgFile']);
if(!$info){ //上传错误提示信息
$this->e($upload->getError());
$this->returnError($upload->getError());
}else{
//存数据库部分
$photo = D('photo');
$photo->name = $info['savename'];
$photo->realName = $info['name'];
$photo->suffix = $info['ext'];
$photo->size = $info['size'];
//...省略部分代码
$id = $photo->add();
// $this->ajaxReturn(array('msg'=>$id),"JSON");
echo json_encode(array('id'=>$id));
}
}
}
因为 thinkphp 自带的 ajaxReturn 返回的数据带有pre标签,会导致ajaxFIleUpload 解析不了,所以用了原生的 echo json_encode() 函数
