Clicking a Button in Safari Web Page

Questions & Suggestions
,
1

I want to create a macros for automated filling the test questions here https://mooc2-ans.chaoxing.com/, I need to click the "Create new test" button.
i do: Activate Safari -> execute JavaScript in Safari {document.getElementsByClass('jb_btn jb_btn_104 fl fs14').click();}
this how the button looks like:
a href="javascript:;" onclick="creatWork();" class="jb_btn jb_btn_104 fl fs14">i class="PlusIcon"新建作业</a

And I works for "yandex.ru" but not here, I'm not familiar with JavaScript, if you know how to solve this problem, please help.

Hey Boris,

Hi Chris, that's true cuz it requires registration, but I can copy and send all the necessary code for you. My question is how to click the button in safari apple events with JavaScript. I'm trying to do -> getElementByClass but but somehow it doesn't work. Is there any other option?

4

Personally I'd use QuerySelector.

I agree with Chris @ccstone: use querySelector. You can do a Forum Search for a number of examples.

I have tried:
document.querySelector("div.bnt_group a[onclick='creatWork();']").click();
document.querySelector("div.bnt_group a[href='javascript\:;']").click();
document.querySelector("div.bnt_group a[href='javascript:;']").click();
document.querySelector(".jb_btn.jb_btn_104.fl.fs14").click();
document.querySelector('.jb_btn.jb_btn_104.fl.fs14' a[onclick='creatWork();']).click();
and honestly lots more, it works fine with another website, both and querySelector and getElementByClass, and ignores me here.

btw

it's <a class=''jb_btn jb_btn_104 fl fs14"...> here, with spaces. Other sites I try class doesn't contain spaces. So i put . instead of spaces but fail.

try this selector:

document.querySelector('a[onclick="creatWork();"]')

This works for me:

var btnElem = document.querySelector('div.fanyaTask div.bnt_group a.jb_btn');
btnElem.click()

based on an OCR of your HTML image, which could contain errors.

If this does not work, please post a broader range of HTML from your web page using Code Block.
Make sure the HTML contains enough UI elements so we can test run/view in a browser.

I don't know what script you are using that causes that error, but when I try the JavaScript I gave you above, it works in the full script that you provided.
I did make some changes to the text display on this web page so I could clearly see which link was being clicked. I also replaced some Chinese text with English.

If I change to a querySelectorAll() it will find all occurrences of that element:

When I run this script:

var btnElemCol = document.querySelectorAll('div.fanyaTask div.bnt_group a.jb_btn');

//--- Click on First Link ---

if (btnElemCol) {
  var linkFound = 'First Link was found';
  btnElemCol[0].click()
} else {  var linkFound = 'First Link was found'; }

linkFound;

I get this:

Note that I made a change to the HTML to call a different function when that link is clicked:

                    <div class="bnt_group">
                        <a href="javascript:;" onclick="creatWorkTest();" class="jb_btn jb_btn_104 fl fs14"><i class="PlusIcon"><img src="/images/add.png"></i><h3>Link 1 -- Create Work Test</h3></a>
                            <a href="/work/library?courseid=216190566&amp;clazzid=35920106&amp;cpi=150304463" class="btnBlue btn_92 fl fs14"><h3>Link 2 -- Open Existing Work</h3></a>
                    </div>
                    <div class="clear"></div>
                </div>


        function creatWorkTest() {
            alert('"CreateWork link was clicked"');
            return;
        }

Here's the test Macro/script that I used:

I copied the code, executed it:

alert(btnElemCol[0]) - undefined.

I have no idea what exactly i do wrong, i am far from programming, but i am able to follow the instruction. Yet, i can do this action for another website but unable to do it for this one, what can go wrong?

No, you did NOT copy my code correctly.

Please try just running the test macro that I provided, without making any changes.

13

of course I first tried your script.Запись экрана 2021-03-29 в 08.39.04.zip (5.3 MB)
Add a video, I run the script, but still nothing.
I have a question, can I execute a function instead of clicking the instance?

14

If you ran my Macro as is, without any changes, and it does not work for you, then I have nothing else to offer. Maybe the language is interfering with our communications and/or the actual script.

Good luck.
