I'm trying to do something as simple as changing the text in my <p> tag from "hello" to "goodbye: but I can't get it to work.
Here is my html
<body>
<div id="passwordBox">
<!-- <div id="title">
<span>PASSWORD GENERATOR</span>
</div> -->
<p id="password">Hello</p>
</div>
</body>
here is my js
document.getElementById('password').innerHTML = "goodbye";
My js is linked correctly in my head. Other functions that I had in there were working correctly. So I'm wondering what the issue is. I'm sure it's something simple that I am just not seeing but I can't figure it out.
HTML execution happens top-down. HTML calls each script it finds while parsing the HTML document. Since you placed your script in "head" the script gets called immediately. When the script is called, your DOM is not yet ready and your script accesses your DOM element returning a null. So load the script after your DOM is loaded completely ie., after body or just before ""
So the ideal code should look like:
<html>
<body>
<div>
<p id="password">Hello</p>
</div>
</body>
<script>
document.getElementByID("password").innerHTML="goodbye";
</script>
</html>
Or you can still load your script from the head, but just add a button along with event listener (onClick) which calls the JavaScript function when the button is clicked.
<!DOCTYPE html>
<html>
<head>
<script>
function changeContent() {
document.getElementById("demo").innerHTML="goodbye";
}
</script>
</head>
<body>
<p id="password">Hello</p>
<button onclick="changeContent()">Try it</button>
</body>
</html>

On our website we use a HubSpot registration form with custom styling that loads in a fancybox popup.
This is how it should look
Our problem is that we need to add an 'on click trigger' (see HTML and JS below) to load the dropdown with the right styling We want to form to work properly without the trigger. Without the click trigger it looks like below:
Also the dropdown isn't working when this form appears.
Our code looks like:
<div class="popup-mask">
<div class="popup sm" id="popup-gartner-get-in-touch">
<h4 class="section-title blue">Get in touch</h4>
<div class="download-form">
<div class="hubpop">
<div class="download-form">
<!--[if lte IE 8]>
<script charset="utf-8" type="text/javascript" src="//js.hsforms.net/forms/v2-legacy.js"></script>
<![endif]-->
<script charset="utf-8" type="text/javascript" src="//js.hsforms.net/forms/v2.js"></script>
<script>
$('a[href="#popup-gartner-get-in-touch"]').click(function() {
hbspt.forms.create({
portalId: "538005",
formId: "190bdb23-c363-4d93-8189-9c7d28782017",
target:'.hubpop',
});
});
</script>
</div>
</div>
</div>
</div><!-- end popup -->
</div><!-- end popup-mask -->
My guess is that you are using some kind of jQuery plugin to style the dropdown. The problem is, your code for that is trying to style something that doesn't exist in the DOM until that trigger is clicked. What you should do is put that jQuery plugin code into the forms onReady function.
hbspt.forms.create({
portalId: '',
formId: '',
onFormReady: function($form) {
// YOUR CODE TO MODIFY THE SELECT DROPDOWN SHOULD GO HERE
console.log($form.find('select'));
}
});
If you're just looking to style the form selects without using a jQuery plugin, you can use this tool to get the css needed to do that.
Given the following html markup structure:
<body>
<div id=Body>
<div>
<iframe>//Data within iframe is generated dynamically
<html>
<head></head>
<body>
<div id="abcdef">
<div></div>
<div></div>
<div></div>
</body>
</html>
</iframe>
</div>
<body>
I want to access the xpath and CSS Selector for <div id="abcdef"> but I am not able to, as it is referring to the internal <html> tag as different frame.
Using
<body>
<div id="Body">
<iframe>//Data within iframe is generated dynamically
<html>
<head></head>
<body>
<div id="abcdef">
<div></div>
<div></div>
<div></div>
</div>
</body>
</html>
</iframe>
</div>
</body>
I was able to successfully select that element with:
//iframe//div[#id = 'abcdef']
Try it out here: http://www.freeformatter.com/xpath-tester.html
However, this is not going to work in the DOM, because of iframe security restrictions. This xpath is correct, but you can test in the chrome dev console with
$x("//iframe//div[#id = 'abcdef']")
and see that you do not get any results. When dealing with HTML documents, your browsers are going to restrict your access to iframes, so you will need to actually grab the iframe, read the html, and then search that html. You will not be able to use an xpath or css selector, as far as I am aware, without getting the content of the iframe and then searching through it as it's own document/element.
Grabbing the iframe like below worked,
driver.switch_to.frame(driver.find_element_by_id('frameid'));
To refer more methods,
Here's a link
Switching to frame, enables you to access all the elements directly.
for above example xpath will be:
//*[#id='abcdef']
Say for example this is my html document.
<html>
<head>
</head>
<body>
<div id="1">
</div>
<div id="2">
</div>
<div id="3">
</div>
</body>
</html>
How in VB.net would would i set the webrowser control to scroll automatically or focus on a specific element?
Thanks
HTML ID and Class names can't begin with a digit, so id="1" is invalid.
What happens with the page after it is rendered is the web browser's business. VB.Net is server side code, so you're better off using JavaScript.
<body onLoad='document.getElementById("myDiv1").focus();'>
After reading a little more closely, I see you specified scrolling in a WebBrowser control. Have a look at this answer.
I'm trying to use Google's Closure library for the HTML editor. I created a goog.editor.SeamlessField but if I enter a word that is too long for the width, it puts a scrollbar in and covers the text. How do I fix this?
This appears to be happening only in Firefox. Here is some HTML that demos the problem:
<!DOCTYPE html>
<html>
<head>
<script type='text/javascript' src='/closure-library/closure/goog/base.js'></script>
<script>
goog.require('goog.dom');
goog.require('goog.editor.SeamlessField');
</script>
<script>
function init() {
var d = goog.dom.getElement('div1');
var f = new goog.editor.SeamlessField(d);
f.makeEditable();
}
</script>
</head>
<body>
<div style='width:150px;'>
<div id='div1'>
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
</div>
</div>
<button onclick='init();'>Create editor</button>
</body>
</html>
DOM fragments generated by this SeamlessField component differ for Chromium and Firefox. The former gets an classic div element, the later issues an iFrame. The scheme has something to do with how Firefox handles content-editable elements. By styling the iFrame, you should be able to avoid the scrollbar.
I read a lot about how to add stuff dynamically in jquery mobile, but I couldn't figure out how to add links.
Currently my solution looks like this:
Add a new Page - with id (id="list-1")
Creating a Link for it (href="#list-1")
This solution works perfectly in static pages, but I want to do it dynamically. I have tried a lot with page() and stuff like that but nothing helped me.
My questions are:
How do I add dynamic links & pages?
Did I choose the right way to use ids & anchors (#list-1) as links or is there another solution for jquery mobile?
Let me know if you need more information
To add dynamic links, I have found the easiest way is to just have an event listener waiting for a click on those links. This event listener then saves any parameters you want to pass into the next page you are visiting. You pass the parameters from the list element to the event listener by just specifying parameters within each "li" element.
(create the HTML for a list dynamically & store it into list-1-html)
$("div#my-page div[data-role=content]").html(list-1-html);
$("div.list-1 ul").listview();
$("div.list-1 ul").listview('refresh');
Then your event listener would look something like:
$('#my-page').delegate('li', 'click', function() {
passedParameter = $(this).get(0).getAttribute('passed-parameter');
});
When jQuery Mobile loads your next page, you'll probably want to load this page dynamically and you'll have this passedParameter variable available to you. To load the page dynamically, just add a listener that waits for JQM to try to load the page:
$('[data-role=page]').live('pageshow',function(e, ui){
page_name = e.target.id;
if (page_name == 'my-page-2'){
(do something with passedParameter)
}
});
This is the workflow I use with jQuery Mobile and it has been working just fine. I'm guessing in future releases, though, that they'll build in some kind of support for passing dynamic parameters to pages.
Any new enhancement to the DOM should be done before the page initializes. But by default JQM automatically initializes the page once the page is load in browser.
Hence first you need to set autoInitializePage property to false and then call initializePage() method after the new page and links are add to the document. Hope this helps.
