我的目标是将类变量设置为会话存储值,如果该值存在于会话存储中。否则,变量将保留其默认值(在ngOnInit中设置)。
private getTableSessionItems = () => {
var tSession = JSON.parse(sessionStorage.getItem('tableSession'));
if(tSession){
for (var property in tSession) {
if (tSession.hasOwnProperty(property)) {
tSession[property]; //Would like to set values equal here this.property = tSession[property]
}
}
console.log('tableSession is true');
}
else{
this.setTableSessionItems();
console.log('nope keep trying', tSession);
}
}
最佳答案
可以动态访问和更新当前类中的属性,如下所示:
private getTableSessionItems = () => {
var tSession = JSON.parse(sessionStorage.getItem('tableSession'));
if(tSession){
for (var property in tSession) {
if (tSession.hasOwnProperty(property)) {
this[property] = tSession[property];
}
}
console.log('tableSession is true');
}
else{
this.setTableSessionItems();
console.log('nope try again', tSession);
}
}
关于javascript - Angular 2获取与此相关的所有变量。在 Controller 中,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/38960886/
