Using appendChild multiple times with the same node in JS

由 我怕爱的太早我们不能终老 提交于 2019-12-04 01:22:12
I'm writing a form validation script for a form with multiple ratings, and I'd like to insert a bit of text that says "give a rating!" for each rating the user misses. I wrote the code below to do this, but I'm running into a problem where the give_rating node is only appended to the last node on the form. I know that this is because appendChild basically moves a node instead of duplicating it, and I tried solving this using cloneNode but that just breaks my JS entirely. Anyway, here's the code. What am I doing wrong? Thanks for your help, Chris var give_rating = document.createElement('span')

how can I remove my appended script because it causes some problems in my app. This is my code to get my script var nowDate = new Date().getTime(); var url = val.redirect_uri + "notify.js?nocache=" + nowDate + "&callback=dummy"; var script = document.createElement('script'); script.src = url; document.body.appendChild(script); Then I have an auto load function, that causes to create another element script. I want to get rid of the previous element that was appended before another element is added. I did some more tests, and before you'll get a correct answer to your question (hope there is a

Javascript appendChild onload event

由 不羁岁月 提交于 2019-12-02 03:37:53
I'm appending the dynamically created image element to document. var img = new Image(); img.src = 'test.jpg', img.onload = function() { var addedImg = container.appendChild(img); console.log(img.width); //old width. } The problem here is the fact if I take image dimensions right after container.appendChild(img) it returns the source file dimensions because the appendChild has not finished yet(not repainted?) and dimensions are not re-calculated. var addedImg = container.appendChild(img); console.log(img.width) //returns original width of the image So, I'm wondering if it is possible to catch

Safari and Chrome doesn't evaluate dynamically added <script> tag at page load

由 雨燕双飞 提交于 2019-12-02 01:17:46
I am writing small JavaScript code which will load external js files at html page loading. I tested 2 ways. Case 1: Used document.write to add <script> tag. It worked for all browsers (IE, FF, Safari, Chrome, Opera). Case 2: Used DOMElement.appendChild to add <script> tag to the <haed> element. Only worked for IE, FF, and Opera. Did NOT work for Safari and Chrome. In both cases, I expected new <script> tag is being inserted before <head> closing tag. So the new <script> tag is evaluated before processing <body>, and by the time window.onload is called, "success" variable should be true. But it

appendChild only works first time

问题 I want to repeatedly append the same stuff to an element via a button and event handler on the same page. The problem I'm encountering is that it only works first time. It does exactly what I want the first time, then fails to do anything on subsequent button presses. I had a bit of a poke around, and it seems that after the first append, the "newstuff.innerHTML" is emptied. After much fruitless searching, I decided to come and ask here. The event handler is firing, the innerHTML of the

How to change root of a node with DomDocument methods?

How to only change root's tag name of a DOM node? In the DOM-Document model we can not change the property documentElement of a DOMElement object, so, we need "rebuild" the node... But how to "rebuild" with childNodes property? NOTE: I can do this by converting to string with saveXML and cuting root by regular expressions ... But it is a workaround, not a DOM-solution. Tried but not works, PHP examples PHP example (not works, but WHY?): Try-1 // DOMElement::documentElement can not be changed, so... function DomElement_renameRoot1($ele,$ROOTAG='newRoot') { if (gettype($ele)=='object' && $ele-

getElementsByClass and appendChild

由 纵然是瞬间 提交于 2019-12-01 04:11:42
just brushing up on my javascript skills and trying to figure out why getElementsByClass isn't working for my code. The code is pretty simple. Upon clicking a button "clicky", the script will create a child h1 element of div. It works perfectly fine when I use getElementById and changing the div class to Id but doesn't work when I change it to class. I've tried, getElementsByClassName, getElementsByClass, getElementsByTagName and changing the div to the appropriate attribute but no luck. <!doctype html> <html> <body> <p>Click on button to see how appendChild works</p> <button onclick=

The Submit Form I have has the name, email, and phone number fields. Of course, I want to insert line break between the three. I tried to insert a line break between all three, but only generated one at the end of the form, when my code should appended 3 line breaks, not one.
