【问题描述】:
我正在开发一个具有内置搜索功能的应用程序。但是,当我在模拟器中(以及在运行 Android 5.1 的 Nexus 7 (2012) 平板电脑上)在 Android 5.1 或更低版本上执行搜索时,我收到一条错误消息,指出“未定义不是函数”,这是迭代的第一行通过它必须搜索的列表。为什么这不适用于所有 Android 版本?
这是我的代码:
controllers.js
$scope.vacaturesZoeken = function() {
// Variable is value of search box
var zoekterm = document.getElementById('search_id').value;
// Check whether there is a proper search term in the variable
if (zoekterm.length === 0 || zoekterm.length === 1) {
// Variable is null, this will be used to check in the function
zoekterm = null;
}
// Search function
Vacatures.zoek($scope, zoekterm);
}
services.js
// Defining search function
zoek: function($VacatureZoekLijstscope, zoekterm) {
// Setting variable for found items to 0
searched.length = 0;
// For every item in vacatures
for (var i = 0; i < vacatures.length; i++) {
// When the box is checked to only search for location
if (document.getElementById("locatie_check").checked === true) {
// Here is where is checked whether the variable is null
if (zoekterm === null) {
return false;
}
// When the searchterm is in the location property of an item
else if (vacatures[i].locatie.toLowerCase().includes(zoekterm.toLowerCase())) {
// Add item to variable
searched.push(vacatures[i]);
}
}
谁能告诉我在 5.1 或更低版本的 Android 设备上使用它有什么问题?提前致谢!
