将变量从jQuery ajax传递到nodejs
问题描述:
我正在尝试将jQuery中的变量传递给nodejs,但是我没有得到正确的结果,nodejs返回[object Object].如何在nodejs端返回字符串变量.
i am trying to pass a variable from jQuery to nodejs, but i am not getting the right results, nodejs returns [object Object]. how can it return a string variable on nodejs side.
$('.test').click(function(){
var tsId = "Hello World";
alert(tsId);
console.log(tsId);
$.ajax({
'type': 'post',
'data':tsId,
'url': '/test/testing',
'success': function (data) {
alert(data);
}
})
});
router.post('/testing', function(req, res) {
var tsID = req.body;
console.log("stsID "+tsID );\\ outputs [object Object]
});
答
我建议您使用这种方式:
I recommend you to use this way:
您应该在ajax data
中传递一个对象,该对象包含您的 Hello World
字符串.
You should pass an object in ajax data
, which contains your Hello World
string.
$.ajax({
type: 'post',
data:{str:tsId},
url: '/test/testing',
success: function (data) {
alert(data);
}
});
在node.js文件中使用以下命令:
In node.js file use this:
router.post('/testing', function(req, res) {
var tsID = req.body;
console.log("stsID "+tsID.str );
});
