如何在jquery中使用javascript变量

Question

I want to use a input parameter of a javascript function inside jquery command.

function logInEmail(value){
    var ati = $("input[name=" + this.value + "]").val();
    if(ati.length == 0){
        alert("Email cant be empty");
        return false;
    }else{
        return true;
    }
}

What is the best way to do it?

Answer 1

Since you've assigned value as the logInEmail function parameter, you can use:

var ati = $("input[name=" + value + "]").val();

instead of:

var ati = $("input[name=" + this.value + "]").val();

Answer 2

Remove "this" in javascript parameter variable as given below ( value instead of this.value ).

function logInEmail(value){
    var ati = $("input[name=" + value + "]").val();
    if(ati.length == 0){
        alert("Email cant be empty");
        return false;
    }else{
        return true;
    }
}
