这可能是一个重复的问题，但我坚持解析 json。因为我是 jQuery 的中级，所以我遇到了这个问题。
我正在使用 CakePhp 实现自动完成。
我的响应函数返回正确的 json。这是我的功能
public function jsonSongs() {
$json_output = '';
$role = $this->Auth->user('role');
$userId = $this->Auth->user('id');
$condition = array("Song.name LIKE " => "%" . $this->request->data['Song_name'] . "%");
$song_name = $this->Song->find('list', array('conditions' => $condition, 'limit' => $this->request->data['Song_maxRows'], 'recursive' => '-1', 'order' => 'Song.name'));
foreach ($song_name as $key => $name) {
$json_output[] = array("id" => $key, "label" => $key." - ".$name, "value" => $name);
}
echo json_encode($json_output);
$this->layout = $this->autoLayout = $this->autoRender = false;
}
返回的 json 是
[{"id":8,"label":"8 - .Dhal gayaa aafataab ai saaqii","value":".Dhal gayaa aafataab ai saaqii"},{"id":32,"label":"32 - a.nga.DaaI par a.nga.DaaI letii hai raat judaaI kii","value":"a.nga.DaaI par a.nga.DaaI letii hai raat judaaI kii"},{"id":34,"label":"34 - aa.Nkh ko jaam samajh baiThaa thaa a.njaane me.n","value":"aa.Nkh ko jaam samajh baiThaa thaa a.njaane me.n"},{"id":35,"label":"35 - aa.Nkh se aa.Nkh milaa baat banaataa kyuu.N hai","value":"aa.Nkh se aa.Nkh milaa baat banaataa kyuu.N hai"},{"id":36,"label":"36 - aa.Nkh se duur naa ho dil se utar jaayegaa","value":"aa.Nkh se duur naa ho dil se utar jaayegaa"},{"id":37,"label":"37 - aa.Nkho.n kaa thaa qasuur naa dil kaa qasuur thaa","value":"aa.Nkho.n kaa thaa qasuur naa dil kaa qasuur thaa"},{"id":38,"label":"38 - aa.Nkho.n me.n jal rahaa hai kyuu.N bujhataa nahii.n dhu.Naa","value":"aa.Nkho.n me.n jal rahaa hai kyuu.N bujhataa nahii.n dhu.Naa"},{"id":39,"label":"39 - aa.Nkho.n se yuu.N aa.Nsuu .Dhalake","value":"aa.Nkho.n se yuu.N aa.Nsuu .Dhalake"},{"id":40,"label":"40 - aadamii aadamii ko kyaa degaa","value":"aadamii aadamii ko kyaa degaa"},{"id":41,"label":"41 - aae hai.n samajhaane log","value":"aae hai.n samajhaane log"},{"id":43,"label":"43 - aah ko chaahiye ik umr asar hone tak","value":"aah ko chaahiye ik umr asar hone tak"},{"id":44,"label":"44 - aaho.n me.n hai asar magar farq asar asar me.n hai","value":"aaho.n me.n hai asar magar farq asar asar me.n hai"}]
最后我的jquery函数是..
$(function () {
function log(message) {
$("<div/>").text(message).prependTo("#log");
$("#log").scrollTop(0);
}
$("#song").autocomplete({
source: function (request, response) {
$.ajax({
minLength: 2,
method: "post",
url: "<?php echo HTTP_PATH; ?>/songs/jsonSongs",
dataType: "jsonp",
data: {
'Song.maxRows': 12,
'Song.name': request.term
},
success: function (data) {
var obj = $.parseJSON(data);
alert( obj.id === "8" );
response($.map(data, function (item) {
return {
label: item.label,
value: item.id
}
}));
}
});
},
select: function (event, ui) {
log(ui.item ?
"Selected: " + ui.item.label :
"Nothing selected, input was " + this.value);
},
open: function () {
$(this).removeClass("ui-corner-all").addClass("ui-corner-top");
},
close: function () {
$(this).removeClass("ui-corner-top").addClass("ui-corner-all");
}
});
});
我想显示建议，当用户单击它刚刚写入隐藏文本框的任何内容时。我什至无法提醒我的json。
