A <canvas> element inside a <div> disappears. What gives?


Tag : jquery-ui , By : cynix

around this issue It may be that your canvas has no height and the div is collapsing into an invisible horizontal line and is not displaying overflow. To get a better answer you'd need to post your html.

Why does an element inside another element not disappear when the larger element disappears?

hope this fix your issue CodePen , You need to add
overflow: hidden;
function openNav() {
    document.getElementById("mynav").style.width = "100vw";
}
 function closeNav() {
    document.getElementById("mynav").style.width = "0vw";
}
html,body{
    height:100vh;
    background:grey;
    font-family: 'Special Elite', cursive;
    display:flex;
    align-items:center;
    justify-content:center;
    overflow:hidden;
   }
  .item{
  font-size:100px;
  }
  .nav{
  z-index:1;
  height:100%;
  width:0;
  position:fixed;
  top:0;
  left:0;
  background:#111;
  transition: 0.5s;
  overflow: hidden;
  }
  .open{
  position:fixed;
  left:0;
  top:0;
  padding:20px;
  font-size:30px;
  }
  .open:hover{
  color:#f1f1f1;
  }
  .close{
  position:absolute;
  top:0;
  right:0;
  padding:20px;
  color:#818181;
  font-size:60px;

  .close:hover{

python selenium Chain for loop (loop inside a loop ) to iterate element


Tag : python , By : Alpinfish

This might help you I suspect your issue lies in the second to last line of the inner loop where you are clearing the #fromDate. The inner loop only sets the #toDate and so if you clear the #fromDate, it won’t get set until the inner loop finishes. Rather, you should only clear the #toDate in the inner loop and then, after the inner loop finishes, in the outter loop, clear the #fromDate. For example:
for date1 in fromDates:
    # set fromDate
    for date2 in toDates:
        # set toDate
        # do thing
        # clear toDate
    # clear fromDate
assert(len(dates_from) == len(dates_to))
for i in range(len(dates_from)):
    date1 = dates_from[i]
    date2 = dates_to[i]
    # use dates 
for list in lists:
    select.select_by_visible_text(list)
    for i in range(len(date_from)):
        date1 = date_from[i]
        date2 = date_to[i]
        browser.find_element_by_css_selector('#fromDate').send_keys(date1)
        browser.find_element_by_css_selector('#toDate').send_keys(date2)
        browser.find_element_by_css_selector('#get').click()
        browser.execute_script("window.scrollTo(150, document.body.scrollHeight);")
        browser.find_element_by_css_selector('html body div#container div.content_big div#wrapper_btm div.main_content div.content div.archives div#replacetext.tabular-data-historic table tbody tr.alt td a.historical-csv-downld').click()
        browser.find_element_by_css_selector('#fromDate').clear()
        browser.find_element_by_css_selector('#toDate').clear()

DOM element mysteriously disappears after being accessed inside setTimeout

Hope this helps So yeah, as said in the comments, and as I kinda guessed: since error-flag is the child of the error-container, and you clean out error-container with errorContainer.textContent = "", the flag will be gone from the DOM. :)

Python, Selenium, how can i exit from while loop after an element disappears?


Tag : python , By : S. Fenz

To fix this issue You can use the error itself to know if the element has disappeared. You just need to handle it and break the loop:
    previous_value = None
    while True:
        try:
            current_value = browser.find_element_by_xpath('//*[@class="cell progress-name text-center ng-star-inserted"]')
        except NoSuchElementException: # the element wasn't found
            break # exit from the loop

        if previous_value:
            if current_value.text != previous_value:
                print(current_value.text)
                previous_value = current_value.text

        else:
            print(current_value)
            previous_value = current_value.text

        time.sleep(1)
previous_value = None
    while True:
        current_value = browser.find_elements_by_xpath('//*[@class="cell progress-name text-center ng-star-inserted"]')
        if not current_value:
            break # the list is empty

        if previous_value:
            if current_value.text != previous_value:
                print(current_value.text)
                previous_value = current_value.text

        else:
            print(current_value)
            previous_value = current_value.text

        time.sleep(1)
