我有3个selectBox可用的场景每个selectBox选项根据其他SelectBoxoptions进行更改，如果我们选择其他selectBox选项，如何动态更改选项
我的JSON格式::
[
{
"projectname": "test1",
"scenarioList": [
{
"scenarioName": "test_scenario1",
"versionList": [
0.1,
0.2,
0.3,
0.4
]
},
{
"scenarioName": "test_scenario2",
"versionList": [
0.1,
0.2
]
}
]
},
{
"projectname": "test2",
"scenarioList": [
{
"scenarioName": "test2_scenario1",
"versionList": [
0.1,
0.3
]
}
]
}
]

$scope.load=function(){
$scope.graph=GraphData;
console.log("data :::"+$scope.graph);
$scope.compare_projectName=$scope.graph[0].projectname;

最佳答案
以下代码可能适合您：
var userModule = angular.module("UserModule", []);
userModule.controller("dashboardController", ["$scope",
dashboardControllerFun]);
function dashboardControllerFun($scope) {
$scope.firstSelect = '0';
$scope.secSelect = '0';
$scope.thSelect = '0';
$scope.graph = [];
$scope.graph =
[
{
"projectname": "test1",
"scenarioList": [
{
"scenarioName": "test_scenario1",
"versionList": [
0.1,
0.2,
0.3,
0.4
]
},
{
"scenarioName": "test_scenario2",
"versionList": [
0.1,
0.2
]
}
]
},
{
"projectname": "test2",
"scenarioList": [
{
"scenarioName": "test2_scenario1",
"versionList": [
0.1,
0.3
]
}
]
}
