CasperJS : dropdown list; select an option, code w

Question

Here my problem : I'm in a specific case where I try to set the option of a select dropdown list. I usually use this.mouse.up() + this.mouse.down() but I can't in this case because this behavior doesn't work on the website with webkit (you can compare the two with google chrome and Firefox).

Here the url : I want to set the field 'ANNEE' to a year, 2008 in my example

My code : (my function changes the HTML and launches the change() event)

//custom function
casper.fillSelect = function(selectSelector, optionText){
    this.evaluate(function(sel,setByText) {
        if ("createEvent" in document) {
            var evt = document.createEvent("HTMLEvents")
                ,x = document.querySelectorAll(sel + ' > option')
                ,l = x.length
                ;
                evt.initEvent("change", false, true);

            for (i=0; i<l; i++){
                if(x[i].textContent.indexOf(setByText) !== -1){
                    console.log(x[i]);
                    console.log(x[i].getAttribute('value'));
                    x[i].setAttribute('selected', true);
                    x[i].parentNode.dispatchEvent(evt);
                }
            }
        }
        else {console.log("error with fillSelect");}
    },selectSelector, optionText);
};

//event
casper.test.on('fail', function(failure) {
    casper.capture('fail.png');
});

/*************************************** Tests *****************************************************/
casper.test.begin('\n********* Compare : ***********', function (test) {
    "use strict";
    casper.start()
    .thenOpen("http://www.linternaute.com/voyage/climat/paris/ville-75056",function(){
        casper.fillSelect('fieldset.fcNeutre > div.odSelect:nth-of-type(2) > select', '2008');
    })
    .waitForUrl(/2008/, function(){
        this.capture('fail2.png');
        this.test.assertSelectorHasText("h2", "maximales");
        this.test.assertSelectorHasText("h2", "minimales");
        this.test.assertSelectorHasText("h2", "Paris");
        this.test.assertSelectorHasText("h2", "Le soleil");
        this.test.assertSelectorHasText("h2", "La pluie");
        this.test.assertExists("tspan");
        this.test.assertExists("div.marB20");
        this.test.assertNotEquals(this.fetchText("div.marB20 > table > thead > tr > th"), "", "Table first data not empty");
    })
    .run(function() {
            this.test.comment('--- Done ---\n');
            test.done();
    });
});

And the equivalent to my casper custom function, you can execute it in the browser :

var fillSelect = function(sel,setByText) {
    if ("createEvent" in document) {
        var evt = document.createEvent("HTMLEvents")
            ,x = document.querySelectorAll(sel + ' > option')
            ,l = x.length
            ;
            evt.initEvent("change", false, true);

        for (i=0; i<l; i++){
            if(x[i].textContent.indexOf(setByText) !== -1){
                //console.log(x[i]);
                //console.log(x[i].getAttribute('value'));
                x[i].setAttribute('selected', true);
                x[i].parentNode.dispatchEvent(evt);
            }
        }
    }
    else {console.log("error with fillSelect");}
};

fillSelect('fieldset.fcNeutre > div.odSelect:nth-of-type(2) > select', '2008');

So it works in FF, Google Chrome, with slimerJS, but not with PhantomJS ... help please, if you have another idea to just select one option in this 'ANNEE' field, with casper+phantom, I take !

Could it be a problem of browser compatibility?

It's strange because in the same website, sometimes it works with other 'select', identical to this one ...

So my final solution (thanks to sudipto)

casper.fillSelect = function(selectSelector, optionText){
    this.evaluate(function(sel, val) {
        jQuery(sel).find("option:contains('" + val + "')").attr('selected', true).change();  
    }, selectSelector, optionText);
};

casper.fillSelect('fieldset.fcNeutre > div.odSelect:nth-of-type(2) > select', '2008');

Since the page already has jQuery in it, I wrote this code and the capture as well as currentUrl shows the change happening. Jquery is able to raise the event correctly. I guess.

I hope you can extract the necessary code from this:

casper.on("load.finished", function (status) {
    if (status !== "success") {
        console.log('Failed to load page.');
    }
    else {

        var thisurl = casper.getCurrentUrl();
        window.count = (window.count || 0)+1;
        casper.capture('loaded'+window.count+'.png');

        if (window.count ==1) {
            casper.evaluate(function(sel, val){

                jQuery(sel).find("option:contains('"+val+"')").attr('selected', true);  
                jQuery(sel).change();

            }, 'fieldset.fcNeutre > div.odSelect:nth-of-type(2) > select', 2008);
        }

        console.log('Page loaded.' + thisurl);
        //casper.wait(2000, function(){
    }
});

Best of luck.
