JSON解析问题 [英] Issue with JSON parsing
问题描述
我是一个在jQuery中使用JSON解析的完整菜鸟。以为我收到了回复......我的数据是这样的:
I am a complete noob with JSON parsing in jQuery. Thought I got the response... My data is in this form:
Array(
[1]=>abc,
[3]=>mango,
[4]=>apple,
[5]=>fruits
)
这样我希望此列表显示为自动完成列表。我正在使用。
In this way I want this list to appear as an autocomplete list. I am using.
jQuery("#name").autocomplete( '<?php echo HTTP_PATH.'/songs/sss'; ?>', {
multiple: true,
mustMatch: true,
matchContains: true,
autoFill: false,
dataType: "json",
parse: function(data) {
return jQuery.map(data, function(item) {
return { data: item, value: item.label, result: item.label};
});
},
formatItem: function(item) {
return item.label;
},
formatResult: function(item) {
return item.id;
},
formatMatch: function(item) {
return item.label;
}
});
我希望显示列表时的值,即我的数据中的标签。当我选择标签时,它应该显示标签。但在提交时,它实际上应该提交密钥。
我的意思是我想让它作为HTML的选择框工作。
I want the value when it shows list, i.e. the label from my data. When I select a label then it should show the label. But at the time of submission it should actually submit the key. I mean I want it to work as select box of HTML.
返回JSON
[{"id":1,"label":"Mehdi Hassan"},{"id":2,"label":"Jagjit Singh"},{"id":3,"label":"Suresh Vadekar"}]
推荐答案
你的JSON似乎不是一个数组,只是一个对象(哈希映射)。
查看官方文档:
Your JSON seems to not be an array, just an object (hash map). Check out official docs:
预期数据格式
来自本地数据,网址或回调的数据可以有两个
变体:
The data from local data, a url or a callback can come in two variants:
-
字符串数组:[Choice1,Choice2]
An Array of Strings: [ "Choice1", "Choice2" ]
具有标签和值属性的对象数组:[{label:Choice1,value:value1},
...]
An Array of Objects with label and value properties: [ { label: "Choice1", value: "value1" }, ... ]
在您的情况下,它应采用以下格式:
In your case it should be in the following format:
[
{"1":"Shad.aab"},
{"158":"Adadad"},
{"159":"Asdadad"},
{"166":"Abbas"},
{"167":"Sdadad"},
{"171":"Shadaab Please check it out"},
{"173":"Check This Please"},
]
(请记住,左侧是标签,右侧值,我想在您的数据中,所有都应该反转......)
(Remember that left side is label, right value, I suppose in your data, all should be reversed...)
