Why does the javascript code in AngularJS2 fire too early and appear to not be functioning properly?

I am facing an issue with my JavaScript script. Even though I have experience in programming with JavaScript before, this problem seems to be new. I am currently working on a website using Angular and JavaScript, but it's not functioning properly. Firstly, when I try to include <script></script> in the component template, it doesn't run at all. Another problem is that I had to link an external script in the index file, which looks like this:

$(window).load(function()
{
    $(".home_page_well").css({opacity:0.5});
    $("#system_epop_h6").hide();
    $("#kto_moze_korzystac_h6").hide();
    $("#co_zrobic_uzytkownik_h6").hide();
});

The HTML structure appears as follows:

<div class="col-sm-12 well home_page_well system_epop">
                <img src="assets/img/question_mark.png"  alt="Co to jest?" class="img-rounded home_img center-block"/>

                <h4>
                    CZYM JEST SYSTEM EPOP?
                </h4>
                <h6 id="system_epop_h6">
                    System EPOP jest platformą pozwalającą na łatwy dostęp do wszystkich danych, które posiada przychodnia. Upraszcza także rejestrację do lekarza
                </h6>
            </div>
            <div class="col-sm-12 well home_page_well kto_moze_korzystac">
                <img src="assets/img/question_who.png"   alt="question_who" class="img-circle home_img center-block"/>

                <h4>
                    KTO MOŻE KORZYSTAĆ Z EPOP?
                </h4>
                <h6 id="kto_moze_korzystac_h6">
                    Wszyscy pacjenci przychodni a także jej pracownicy.
                </h6>
            </div>
            <div class="col-sm-12 well home_page_well co_zrobic_uzytkownik">
                <img src="assets/img/palm_shake.png"  alt="palm_shake" class="img-circle home_img center-block"/>

                <h4>
                    CO ZROBIĆ, ABY STAĆ SIĘ UŻYTKOWNIKIEM SYSTEMU
                </h4>
                <h6 id="co_zrobic_uzytkownik_h6">
                    Należy się zarejestrować poprzez panel pacjenta, lub zadzwonić do przechodni wtedy wszystkie operacje przeprowadzi wykwalifikowany personel.
                </h6>
            </div>

Your assistance in resolving why my script doesn't run in the component template URL would be greatly appreciated. Thank you in advance :)

Answer №1

Implement the timeout feature using Jquery to delay the execution of a specific event.

setTimeout(function(){
 $(".banner_image").css({opacity:0.7})
 $("#promo_title").hide()
 $("#discount_code").hide()
 $("#product_details").hide()
}, 1500);

With this implementation, the issue of premature script execution will be resolved.

Answer №2

RESOLUTION: To solve this issue in your TypeScript file, you need to include the following:

ngOnInit()
{

   //implement something like my_init_function(); which should be defined in Your JavaScript file

}

This method ensures that the function set_home_page(); is executed once Angular has finished its task.
