Posted 2020-09-26 lijun8637

let hasObj = false;
for (let i in data.imgPathInfo){
　　hasObj = true;
　　break;
}
if(!hasObj){
　　_this.$message.error(‘图片路径对象为空！‘);
}

jq

function isEmptyObject(e) {
　　var t;
　　for (t in e)
　　　　return !1;
　　return !0
}

console.log($.isEmptyObject({"re": 2})); //false

console.log(isEmptyObject()); //true
console.log(isEmptyObject({})); //true
console.log(isEmptyObject(null)); //true
console.log(isEmptyObject(23)); //true
console.log(isEmptyObject({"te": 2})); //false
