JS typeof 与 instanceof

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> JS中常用来判定变量类型的两个函数为 typeof 和 instanceof typeof 的结果有 undefined, number, boolean, string, function, object[ null, Array, String, Date.....] 要注意的地方是 typeof null的结果为object， null在js中是一种特殊的对象，而非等同于 undefined null 和 undefined 并不是等价的 var tmp = null; // 虽然tmp是null，但我也定义了 var undef; //声明但没定义 alert(typeof tmp); // object alert(typeof undef); // undefined 所以判断一个值是不是null的时候直接用 tmp == null即可，切勿使用typeof，null是一种特殊的对象 // 标量 // typeof 123; // number typeof 'string'; // string typeof true; // boolean // 函数 // typeof function(){}; //function // 对象 // typeof new String('string');

babel 编译后 this 变成了 undefined

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 最近有在用webpack，使用了babel这个模块来编译js jsx文件，但是发现文件编译后this变成了undefined。 源文件 module.exports = React.createClass({ render: () => { return (<div>{this.props.name}</div>); } }); 编译后 module.exports = React.createClass({ render: () => { return (<div>{undefined.props.name}</div>); } }); 这个原因是因为webpack规则中babel用了es2015的编译规则 { test: /\.jsx?$/, loader: "babel", query: { presets: ['react', 'es2015'] } } 解决的方法是这样修改 module.exports = React.createClass({ render: function(){ return (<div>{this.props.name}</div>); } }); 其根本的原因是es2015的箭头函数，这个一个不能忽视的问题 普通function函数和箭头函数的行为有一个微妙的区别

String subscript out of range. String size is unknown and looping string until null

由 ♀尐吖头ヾ 提交于 2020-01-07 04:38:34
问题 #include<iostream> #include<cmath> #include<iomanip> #include<string> using namespace std; int main() { string word; int j = 0; cin >> word; while(word[j]){ cout << "idk"; j++; } cout << "nope"; system("pause"); return 0; } This is just a little trial program to test this loop out. The program I am working on is about vowels and printing vowels out from a sequence determined by the user. The string isn't defined until the user types in. Thank you for your guys help in advance. 回答1: Try this

findpreference undefined type

问题 I am trying to set a value to a ListPreference and always get the error message: The method findPreference(String) is undefined for the type new DialogInterface.OnClickListener(){} This is my code: ListPreference lp = (ListPreference) findPreference("enableTranslations"); lp.setValue(""); Thanks 回答1: You simply call findPreference in wrong place (in OnClickListener). Call it in method of class that has findPreference method (PreferenceManager or PreferenceActivity) or on object of such type.

Firebase value is undefined when it is not supposed to be

由 狂风中的少年 提交于 2020-01-06 06:06:45
问题 I am working on a firebase project. During testing the return user.val().name; will return an undefined value however the console.log(user.val().name) will return the actual string stored in the .name field. Why is that. Also even if assign the user.val().name to a variable, the variable remains undefined.Please help figure out why this happens. I am printing it to a csv. Here is my code: var database = firebase.database(); var ref2 = database.ref('information/'); var id; var name; ref2.on(

How to use class defined in a separate header within a namespace

问题 I have a namespace in which I'd like to define a class.
