guys i know its dummy questions but i spent hours on this and cant reach .. I am trying to pass a JSON array to JSP via an AJAX call in another JS file.伙计们,我知道它的愚蠢问题,但我在这个问题上花了几个小时却无法解决..我试图通过另一个 JS 文件中的 AJAX 调用将 JSON 数组传递给 JSP。 It is giving me a 404 error.它给了我一个 404 错误。 Any help would be appreciated.任何帮助,将不胜感激。 Here is my code:这是我的代码:
function GridLibrary(fileName) {
this.fileName = fileName;
}
GridLibrary.prototype = {
setFileName : function(fileName) {
this.fileName = fileName;
},
getFileName : function() {
return this.fileName;
}
};
GridLibrary.prototype.display = function() {
$.ajax({
url : this.getFileName(),
dataType: "json",
error : function(that, e) {
console.log(e);
},
success : function(data) {
alert("found");
}
});
};
var Json = [{
"id": 1,
"name": "name1",
"age" : 10,
"feedback": "feedback1"
}, {
"id": 2,
"name": "name2",
"age" : 90,
"feedback": "feedback2"
}, {
"id": 3,
"name": "name3",
"age" : 30,
"feedback": "feedback3"
}, {
"id": 4,
"name": "name4",
"age" : 50,
"feedback": "feedback4"
}];
new GridLibrary(Json).display();
You need to have a valid url to send the values to the backend:您需要有一个有效的 url 才能将值发送到后端:
function GridLibrary(url, data) {
this.url = url;
this.data = data;
}
GridLibrary.prototype = {
setData: function(data) {
this.data = data;
},
getData: function() {
return this.data;
},
setUrl:function(url){ this.url = url; },
getUrl:function(){ return this.url; },
display : function() {
$.ajax({
url: this.getUrl, // <----the url where you want to send the data
data:this.getData, //<----should be the array data
dataType: "json",
contentType:"application/json", // <----add this contentType
error: function(that, e) {
console.log(e);
},
success: function(data) {
alert("found");
}
});
}
};
var url = '/url/to/send',
data = [{}....];
new GridLibrary(url, data).display();
