Mad*_*u K 8 underscore.js angularjs
在我的angularjs应用程序中有一个对象数组,如下所示:
$scope.rowData = [{
"expNum": "678",
"itemHr": "10",
"highRe": "C"
}, {
"expNum": "978",
"itemHr": "3",
"highRe": "Y"
}]
现在在单击事件上,我需要将数组中每个对象的'itemHr'更新为一些新值,让我们说(25).我不想创建新的对象数组而只修改现有的对象.如果我们可以使用angularjs实用程序来执行它或下划线库,那么对我来说都很好.任何人都可以帮助我.

为什么vanila js没有for循环？
for(var i = 0; i<$scope.rowData.length; i++)
{
$scope.rowData[i].itemHr = 25;
}
或下划线
_.each($scope.rowData, function(item){ item.itemHr = 25;});
或有角的
angular.forEach($scope.rowData,function(item){ item.itemHr = 25; });
var app = angular.module("myApp", ['ui.bootstrap']);
app.controller("maincontroller", function($scope) {
$scope.rowData = [{
"expNum": "678",
"itemHr": "10",
"highRe": "C"
}, {
"expNum": "978",
"itemHr": "3",
"highRe": "Y"
}];
$scope.update = function(){
for(var i = 0; i<$scope.rowData.length; i++)
{
$scope.rowData[i].itemHr = 25;
}
}
