我想要一个指令,它将根据类别层次结构名称数组呈现按钮列表。如果一个按钮没有更多的孩子,或者如果它有孩子,则会选择该类别将深入到下一个级别。
I / P:
[{name:electronics''},{name:'hobbies'},{name:'electronics | computers'},{name:'electronics | computers | software'},{name:'electronics | headphones' }]
上面的阵列将首先呈现2个按钮,单击电子设备将呈现新按钮:电脑和耳机等。
我试过了:
controller: ['$scope', function($scope) {
$scope.category= [];
$scope.init = function() {
for(var index=0; index<$scope.option.data.length; index++) {
if($scope.option.data[index].name.indexOf("|") === -1){
$scope.category.push($scope.option.data[index]);
}
}
}
$scope.init();
$scope.drillDown=function(value){
// console.log(value);
var count = 0;
var arrVal=[];
arrVal=value
$scope.category= [];
for(var index=0; index<$scope.option.data.length; index++) {
if($scope.option.data[index].name.indexOf(value + "|") !== -1){
for(var i=0; i< $scope.option.data[index].name.length; i++){
if($scope.option.data[index].name[i] == '|'){
count+=1;
}
}
if(count === 1){
$scope.category.push($scope.option.data[index]);
}
count = 0;
}
}
}
}]
答案 0 :(得分:0)
检查以下代码段:
$scope.drillDown = function(event){
$scope.delimiter = '|';
$scope.buttons = [];
$scope.delimiterCount = (event.n.split($scope.delimiter).length - 1);
$scope.flagAll = false;
angular.forEach($scope.option.data,function(value,index){
if($scope.option.data[index].name.indexOf(event.n+$scope.delimiter) !== -1){
$scope.splitData = $scope.option.data[index].name.split($scope.delimiter);
if($scope.flagAll == false){
$scope.buttons.push("All "+$scope.splitData[$scope.delimiterCount]);
$scope.flagAll = true;
}
if(($scope.splitData.length-1) > ($scope.delimiterCount+1)){
//$scope.buttons.push("All "+$scope.splitData[$scope.delimiterCount]);
}
else{
$scope.buttons.push($scope.option.data[index].name);
}
}
});
}
