H5 段，无法获取 e.currentTarget.dataset.

template 绑定 <text :data-productInfo="product"....
methods 调用 add function(e) { console.log(e); .........

在Chrome 控制台中报错 ReferenceError: e is not defined
微信开发者工具，运行正常。

这是什么原因??? 如何解决。

data-productInfo这种绑定方式是微信的做法，不是vue的做法。
应该直接在vue的方法里传入参数。

谢谢答复，请问如何在 uniapp 中用vue的方法里传入参数?

已解决: 事件绑定用 @click="addcart(product)" H5 和小程序都能用

q***@foxmail.com - 天方夜谭之天马行空

module.exports = {  
    factory:function(e){  
        let attrs=e.obj.$attrs;  
        let temattr={};  
    for (var attr in attrs){  
            var key=attr.substring(attr.indexOf('-')+1,attr.length);  
            temattr[key]=attrs[attr];  
        }  
        var obj={  
            detail:e.data,  
            currentTarget:{  
                dataset:temattr  
            }  
        };  
        console.log(obj);  
        return obj;  
    }  
}

input: function() {  
var that=this;  
that.$emit('input',util.factory({  
    obj:that,  
    data:{  
        value: that.$data.value,  
    }  
}));  
},  
change: function() {  
var that=this;  
that.$emit('change',util.factory({  
    obj:that,  
    data:{  
        value: that.$data.value,  
    }  
}));  
},  
<textutil tem="大幅度" data-val2="hhh" data-val3="hhh" data-val="hhh" @input="textinput" value="哈哈哈哈的飞哥电饭锅豆腐干豆腐干豆腐高度" :show="textutil"></textutil>

再符一个：

        setData(e){  

            let data=that.$data;  

            for(var prop in e){  

                data[prop]=e[prop];  

            }  

        },
