plus.camera.getCamera().captureImage 方法执行后webview被关闭，重新打开

分类：HTML5+

一个拍照上传的功能。执行plus.camera.getCamera().captureImage，拍照完成后回调函数老是不能执行。后来调试发现，打开相机的时候，当前页面的webview 被关闭重新打开了。请问是代码写的不对吗？有什么解决办法？
js代码如下

var agencyLongitude;  
var agencyLatitude;  
var customer_id;  
var plan_id;  
var visitPhotos;  
var state;  
var customer_name;  
var company_name;  
var area_name;  
var address;  
var customer_phone;  
var photoImgs = new Array();  
(function(mui, doc, win) {  
    mui.init();  

    //上传门头照片  
    var uploadPhoto = function() {  
        //从照相机获取图片  
//      var photoid = this.id;  
        var photoid = 0;  
        console.log('photoid=' + photoid);  
        plus.camera.getCamera(1).captureImage(function(img){  
            console.log(1);  
            compressImg(img, function(p){  

                var wt=plus.nativeUI.showWaiting("照片上传...");  
                var filename = img.substr(img.lastIndexOf('/') + 1);  
                mui.post(server.url() + '/commons/ajaxuploadbase64.do',  
                        {fileData:p, fileName: filename},  
                        function(result){  
                            if(result.flag=="0"){  
                                photoImgs[photoid] = result.data[0].filePath;  
                                doc.querySelector('#takePicture').innerHTML = "<img src=\"" + photoImgs[photoid] + "\" width=\"100%\" height=\"100%\"/></img>";  
                            }else{  
                                //outLine("上传失败："+status);  
                                plus.nativeUI.toast("照片上传失败");  
                            }  
                            wt.close();  
                        },  
                        'json'  
                );  
            });  
        },function(e){  
            console.log(e.code);  
            console.log(e.message);  
        },{});  
    };  

    mui.plusReady(function() {  
        var self= plus.webview.currentWebview();  
        plan_id = self.plan_id;  
        customer_id = self.customer_id;  
        console.log(11112222);  
        $("#customer_name").html(self.customer_name);  
        $("#company_name").html(self.company_name);  
        $("#address").html(self.area_name+self.address);  
        if(state != '0'){  
            doc.querySelector("#submitSummary").style.display = 'none';  
        }else{  
            doc.querySelector("#submitSummary").addEventListener('tap',submitSummary);  
            doc.querySelector("#takePicture").addEventListener('tap',uploadPhoto);  
        }  
        doc.querySelector("#takePicture").addEventListener('tap',uploadPhoto);  
        finishLoading();  
    });  
})(mui, document, window);
