How to Login by filling the form in CasperJs

Question

Following is the hlml of the login form that I have

<div class="login_area_user">

            <form method="post" action="https://www.tradus.com/login?dest_url=https://www.tradus.com/cart/select-address" id="user-login">
            <input type="hidden" value="1" name="form_submit">

                <h3 style="display:inline-block;">Already a Member</h3>

                <p id="login-main-center-right-descp">You can use tradus login id and password</p>

                <div class="login-row">
                    <label class="colorBlack">Email / Login*</label>
                    <input class="login-field" type="text" name="name" id="edit-namepopup">
                </div> <!-- [/login-row] -->

                <div class="login-row">
                    <label>Password</label>
                    <input class="login-field" type="password" id="edit-passpopup" name="pass">
                </div> <!-- [/login-row] -->

                <div class="login-row">            
                    <a class="forgotPassword" href="/forgot_password">Forgot your password?</a>
                    <!--input type="checkbox" name="remember" /><span>Remember me</span-->
                </div>

                <div class="login-row">
                    <input class="login-button" value="Login" type="submit">
                </div>

                <input type="hidden" name="op" value="Log in">

            </form>

        </div>

Am using the following code to login :

this.fill('form#user-login', {
        'form_submit':    1,
        'name':    'abc@gmail.com',
        'pass':   'pwd',
        'op':       'Log in'

    }, true);

But I dont thing its doing the thing for me.

Answer 1

casper.waitForSelector("form input[name='name']", function() {
    this.fillSelectors('form#user-login', {
        'input[name = name ]' : 'abc@gmail.com',
        'input[name = pass ]' : 'pwd'
    }, true);
});

Simply use this (see waitForSelector docs ). Firstly, wait for the form to be loaded. Then fill the form using the selectors.

Answer 2

casper.waitForSelector('form', function(){
    this.fill('form', {
    'name': 'abc@gmail.com', 
    'pass': 'pwd'}, true);
});

<!-- wait until a form tag disappears -->
casper.waitWhileSelector('form', function(){
    this.echo('selector is no more!');
});

casper.then(function(){
    this.echo(this.getTitle());
});

In case anyone else finds this.. I used some combination of these answers - my login form was also in an iframe which added some difficulty, but basically the issue I saw (cookie-based login) is that casper was going to the next step before the server could respond and set the cookie. I added some .wait() callbacks to ensure enough time to get that cookie. It may not be foolproof, but I have yet to have an issue with it

Mind you, the cookie needs to be set EVERY CRAWL

casper.start(config.loginUrl, function() {

console.log("Checking login status @ " + config.loginUrl);

// set a wait condition to make sure the page is loaded (particularly iframe in my case) 
this.wait(5000,function(){

    // switch to iframe (won't be necessary for most)
    this.page.switchToChildFrame('login'); 

    // fill out the form 
    this.fillSelectors("form[name='loginForm']",{
        'input#txtUsername' : config.username,
        'input#txtPassword' : config.password
    });

    // click the login button 
    console.log("Logging In...")
    this.click('input.button.login');

    // ** give my crappy dev server 5 seconds to respond
    this.wait(5000,function(){
    console.log('Starting to spider ' + dataObj.start)

    // do yo dance  
    spider(dataObj.start);
    });

Hmmm.. Follow that with:

casper.then(function () {
    this.evaluate(function () {
        $('form#user-login').submit();
    });
});
