Procedure to save a value in cookies using Angular version 2

 

In the following code, we pass three parameters:

1. name - the name of the cookie (that you want to create)
2. value - the value you want to save in the cookie
3. days - expiry days for your cookie

This is a simple live example of how to use a cookie in your application,

GetNames() {
    var strVal = this.readCookie("Angular2_demo");
    var name = this.Registration.Address
    if (strVal == name) {
        alert("hi i am " + name);
    }
};
savecookies() {
    this.createCookie("Angular2_demo", this.Registration.Name, 7);
}
createCookie(name: string, value: string, days: number) {
    var expires = "";
    if (days) {
        var date = new Date();
        date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
        expires = "; expires=" + date.toUTCString();
    }
    document.cookie = name + "=" + value + expires + "; path=/";
}
readCookie(name: string) {
    debugger;
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for (var i = 0; i < ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0) == ' ') c = c.substring(1, c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
    }
    return null;
}
eraseCookie(name: string) {
    this.createCookie(name, "", -1);
} < input type = "text"
class = "form-control"
id = "Name"
name = "Name" [(ngModel)] = "Registration.Name" (blur) = "savecookies()"
placeholder = "Enter Name" > < button type = "submit"
class = "btn" (click) = "GetNames()" > GetNames < /button>
