使用Angularjs获取数组中的值并传值到html页面中显示出来
js页面的数组如下:
var freetrial = [{
goodsid:"xy0001",
imgurl:"img/178jpg",
goodstitle:"好娃娃牌安全椅",
quantity:"10份",
cost:896,
linkt:"sdcx()",
status:0},
{
goodsid:"xy0002",
imgurl:"img/178jpg",
goodstitle:"时尚包",
quantity:"10份",
cost:298,
status:1},
{
goodsid:"xy0003",
imgurl:"img/178jpg",
goodstitle:"好娃娃",
quantity:"10份",
cost:896,
linkt:"sdcx()",
status:0}
];
html页面:
<div class=“xsy” id="xy0001">
<a href="{{sdcx()}}"><img src="{{imgurl}}"></a>
<h1>{{goodstitle}}</h1>
</div>
需要判断的是如果div的id==数组里的goodsid且status=0,就把数组的值传到页面对应的地方。要使用Angularjs来实现,不能使用jQuery。求大神指点要怎么做,如果我的思路不对,有没有其他更好的方法?用来保存数据的数组肯定是需要的,jQuery也不能用。

追问:请问如果我需要在点击这个a标签时,把div的id post出去,让另外一个js页面接收到,然后在数组匹配符合的数组数据输出到html页面。这个要怎么实现?
AngularJs ng-if的用法
123456789101112131415 <!DOCTYPE html><html ng-app><head> <title>checked</title></head><body> <input type="checkbox" ng-model="checked">点击试试 <div ng-if="checked">content</div> <script type="text/javascript" src="/angularminjs"></script> </body></html>
angularjs中关于checkbox的问题
烦恼
我想设置当checkbox选中之后执行一段逻辑代码,我写的是if($scope(checkbox1)checked){`````}但是不行我想问的是这个if逻辑应该怎么写怎么表达他被选中了???

使用angular的$>
<body onload='test()'>
<div ng-app="myApp" ng-controller="formCtrl">
<input type="text" id='aaaa' ng-model="userfirstName"><br>
<button ng-click="showvalue()">获取</button>
</div>
<script>
function test(){
alert(documentgetElementById('aaaa')value);
}
var app = angularmodule('myApp', []);
appcontroller('formCtrl', function($scope) {
$scopemaster = {firstName:"John1", lastName:"Doe"};
$scopeshowvalue = function() {
alert($scopeuserfirstName);
};
$scopeuser = angularcopy($scopemaster);
});
</script>
#简单来说 LabelEncoder 是对不连续的数字或者文本进行编号
from sklearnpreprocessing import LabelEncoder
le = LabelEncoder()
lefit([1,5,67,100])
letransform([1,1,100,67,5])
输出: array([0,0,3,2,1])
#OneHotEncoder 用于将表示分类的数据扩维:
from sklearnpreprocessing import OneHotEncoder
ohe = OneHotEncoder()
ohefit([[1],[2],[3],[4]])
ohetransform([2],[3],[1],[4])toarray()
输出:[ [0,1,0,0] , [0,0,1,0] , [1,0,0,0] ,[0,0,0,1] ]
