How to use string match() with angularJs $scope.search variable
提问by Khaleel
I try to use string match with ignore case sensitivityand my input $scope.searchvariable, but it doesn't work.
我尝试使用忽略大小写敏感度和我的输入$scope.search变量的字符串匹配，但它不起作用。
<input type="text" ng-model="search" autofocus="autofocus">
angular.forEach(groups, function(group, key) {
console.log(group); // => Object contains
if (group.label.match(/($scope.search)/i)) {
result[key] = group;
}
});
Data Object group:
数据对象组：
Object { label: "Transfiguration", articles: Array[1] }
How to use group.lable.match()with $scope.searchcorrectly?
如何使用group.lable.match（）与$scope.search正确？
Many thanks.
非常感谢。

Your regular expression is dynamic so you cannot use /regexp/syntax. You need to create a Regexpobject instead.
您的正则表达式是动态的，因此您不能使用/regexp/语法。您需要创建一个Regexp对象。
angular.forEach(groups, function(group, key) {
console.log(group); // => Object contains
if (group.label.match(new RegExp("(" + $scope.search + ")", "i"))) {
result[key] = group;
}
});
You can probably remove the brackets from the RegExp too.
您也可以从 RegExp 中删除括号。
It is better also to use test()because you aren't interested in the results:
最好也使用，test()因为您对结果不感兴趣：
if(new RegExp($scope.search, "i").test(group.label)) {
Finally, if this is a basic search, putting both parts to lower case and using indexOfshould be more efficient:
最后，如果这是一个基本的搜索，将两个部分都放在小写并使用indexOf应该更有效：
if (group.label.toLowerCase().indexOf($scope.search.toLowerCase()) > -1) {

you can always use javascript in angularjs modules :)
你总是可以在 angularjs 模块中使用 javascript :)
angular.forEach(groups, function(group, key) {
console.log(group); // => Object contains
if (group.label.toLowerCase().indexOf($scope.search.toLowerCase())!=-1) {
result[key] = group;
}
});
This should solve your problem
这应该可以解决您的问题
