我在PHP页面中有这个JSON字符串:
{
"elements": [{
"type": "pie",
"alpha": 0.3,
"animate": [{
"type": "fade"
}, {
"type": "bounce",
"distance": 5
}],
"start-angle": 0,
"tip": "#val# de #total# #percent#",
"colours": ["#d01f3c", "#356aa0", "#C79810"],
"values": [{
"value": 1,
"label": "procesador amd sempron 140"
}, {
"value": 1,
"label": "procesador sempron le130"
}, {
"value": 1,
"label": "procesador amd a4-3300 x2"
}, {
"value": 1,
"label": "procesador intel celeron g530"
}]
}],
"title": {
"text": "Procesadores, Reinicio",
"style": "color: #356aa0; font-size: 20px"
},
"bg_colour": "#FFFFFF",
"x_axis": null
}
我这样称呼它:
$.getJSON("restart_proce.php", function(json)
{
console.log(json);
我需要把它变成这样:
[{'"value'": 1, '"label'": '"procesador amd sempron 140'" }, { '"value'": 1, '"label'": '"procesador sempron le130'" }, { '"value'": 1, '"label'": '"procesador amd a4-3300 x2'" }, { '"value'": 1, '"label'": '"procesador intel celeron g530'" } ]
我正在尝试删除这样的元素:
delete json.elements[3];
但是它不删除任何东西。我怎样才能让它工作?
从数组中删除项:
有几种方法。拼接方法是最通用的:
data.items.splice(3, 1); // Removes three items starting with the 2nd,
splice修改原始数组，并返回您删除的项的数组。
试试这个:
json.elements.splice(3, 1);
看到:Array.splice
直接修改console.log(json)前面的值
json= json.elements[0].values
或者在restart_proce.php php页面echo
echo json_encode($data['elements'][0]['values']); // if associative array is used.
试试这个:
var data = {"result":[
{"FirstName":"Test1","LastName":"User","Email":"test@test.com","City":"ahmedabad","State":"sk","Country":"canada","Status":"False","iUserID":"23"},
{"FirstName":"user","LastName":"user","Email":"u@u.com","City":"ahmedabad","State":"Gujarat","Country":"India","Status":"True","iUserID":"41"},
{"FirstName":"Ropbert","LastName":"Jones","Email":"Robert@gmail.com","City":"NewYork","State":"gfg","Country":"fgdfgdfg","Status":"True","iUserID":"48"},
{"FirstName":"hitesh","LastName":"prajapti","Email":"hitesh.prajapati@phptalent.com","City":"","State":"","Country":"","Status":"True","iUserID":"78"}
]
}
alert(data.result);
delete data.result[3];
alert(data.result);
