cDe*_*eke 2 javascript jquery json
我有一个json文件,我想构建一个表单,该表单允许我在文件中添加/编辑元素。是否有一个jQuery函数/方法,使我能够在外部json文件中发布和追加元素?
不知道这是否有帮助,但是当前的json结构如下:
[ { "cast" : "",
"director" : "",
"genre" : "",
"id" : false,
"nrVotes" : 0,
"plot" : "",
"rating" : 0,
"runtime" : 0,
"title" : "",
"year" : false
},
{ "cast" : "Tim Robbins, Morgan Freeman, Bob Gunton, ",
"director" : "Frank Darabont",
"genre" : "Crime Drama ",
"id" : "0111161",
"nrVotes" : 968510,
"plot" : "Two imprisoned men bond over a number of years, finding solace and eventual redemption through acts of common decency.",
"rating" : 9.3000000000000007,
"runtime" : 142,
"title" : "The Shawshank Redemption",
"year" : "1994"
}]

如果您使用的是jQuery的getJSON或parseJSON(),则可以使用一个JavaScript对象。例如:
$.getJSON( "/test.json", function( data ) {
// now data is JSON converted to an object / array for you to use.
alert( data[1].cast ) // Tim Robbins, Morgan Freeman, Bob Gunton
var newMovie = {cast:'Jack Nicholson', director:...} // a new movie object
// add a new movie to the set
data.push(newMovie);
});

您现在要做的就是保存文件。您可以使用jQuery.post()将文件发送回服务器以为您保存。
更新:发布示例
//inside getJSON()
var newData = JSON.stringify(data);
jQuery.post('http://example.com/saveJson.php', {
newData: newData
}, function(response){
// response could contain the url of the newly saved file
})

在您的服务器上,使用PHP的示例
$updatedData = $_POST['newData'];
// please validate the data you are expecting for security
file_put_contents('path/to/thefile.json', $updatedData);
//return the url to the saved file
