通过js实现跨界面之间传值

A界面传值

 UploadForm: function (param) {
    
    
        var param = {
    
    };
        param.projectID = ProjectID;
        param.Detalid = detalid;
        param.CheckSumid = checksumid;
        var jsonStr = JSON.stringify(param);
        localStorage.setItem("jsonStr", jsonStr)
        learun.layerForm({
    
    
            id: 'UploadModelForm',
            title: '上传界面',
            url: top.$.rootUrl + '/Manage//UploadModelForm?jsonStr=' + escape(jsonStr),
            width: 600,
            height: 400,
            maxmin: false,
            btn: null,
            callBack: function (id) {
    
    
                return top[id].acceptClick(refreshGirdData);
            }
        });
    },

B界面接收值

```javascript
var datastr = request('jsonStr');
