Question

我在数组中存储了一些数据。这将是这样的

       datas[
       password:"dfsdfsd",
       username : "dfgdgdfg55555",

       password:"deep",
       username : "dfgdgdfg56556",

       password:"hello",
       username : "dfgdgdfg65",

       password:"hello1234",
       username : "dfgdgdfg123"
     ]

现在我想用camapare用户名。而我正在尝试它，并希望如果条件为真（带我到另一页）但不知道该怎么做。

  checkCred(){
    var details_array = this.state.datas1 ;
    console.log(details_array);
    for(var i=0; i < details_array.length; i++) {
        var currentObject = details_array[i];
        if (this.email.value === currentObject.username) {
            console.log('yes done it');
            window.location = '/Index';// this is not working and think window.location is stupid methed...
            // please guide me if you have any better idea than this
        }

    }
  }
   <input ref={(e) => this.email = e} name="email" type="email" /><br/>

我做得对吗？

Answer 1

按照预期进行以下更改

var details_array = this.state.datas ;
for(var i=0; i < details_array.length; i++){
 var currentObject = details_array[i];
 if (this.email.value === currentObject.username){
    console.log('yes done');
 }
}

注意：希望您在details_array中有数据。

IF ELSE in react（如果条件正确，请带我到另一页）
