AngularJS-拆分字符串问题 [英] Angularjs - Split String issue

问题描述

我暂时没有眼睛..下面的代码引发错误

I am temporarily devoid of seeing eyes.. The code below throws up an error

错误:value.split不是函数

Error: value.split is not a function

这是angularjs分割简单字符串的一种方法

Is threre an angularjs way of splitting a simple string

var value = "7,9";

$scope.getTemplate = function(value){

    var values = value.split(",");

    value1 = values[0];
    value2 = values[1];

    $scope.templateid = value1;
    $scope.userid = value2;
}

推荐答案

问题似乎是您有一个名为 value 的函数参数，该参数隐藏了外部变量 value .另外，您的函数定义以)而不是} 结尾，这是一个语法错误，不过，我认为这可能与您发布方法有关.代码在这里.

The issue seems to be that you've got a function parameter named value which hides the outer variable, value. Also, your function definition ends with a ) rather than a }, which is a syntax error, although, I believe that's probably just in issue with how you've posted the code here.

您还应该显式声明变量 value1 和 value2 (除非您实际上在函数外声明了它们).

You should also explicitly declare the variables value1 and value2 (unless you have actually declared them outside your function).

尝试以下方法:

var value = "7,9";

$scope.getTemplate = function(){
    var values = value.split(",");

    var value1 = values[0];
    var value2 = values[1];

    $scope.templateid = value1;
    $scope.userid = value2;
};

或者完全摆脱中间变量:

Or get rid of the intermediate variables entirely:

$scope.getTemplate = function(){
    var values = value.split(",");
    $scope.templateid = values[0];
    $scope.userid = values[1];
};

更新根据您的评论，该方法实际上是使用两个参数而不是单个字符串参数来调用的.在这种情况下，根本不需要拆分.试试这个:

Update Given your comments it appears the method is actually being called with two parameters, rather than a single string parameter. In this case there's no need to split at all. Try this:

$scope.getTemplate = function(value1, value2){
    $scope.templateid = value1;
    $scope.userid = value2;
};
