my existing code generates a random webpage from a predetermined list after clicking on a radio button. I want to remove the radio button and create a "a href" in my nav bar to create the same effect.
Here is my current code:
<script type="text/javascript">
function randomlinks(){
var myrandom=Math.round(Math.random()*9)
var links=new Array()
links[0]="http://www.javascriptkit.com"
links[1]="http://www.dynamicdrive.com"
links[2]="http://www.cssdrive.com"
links[3]="http://www.codingforums.com"
links[4]="http://www.news.com"
links[5]="http://www.gamespot.com"
links[6]="http://www.msnbc.com"
links[7]="http://www.cnn.com"
links[8]="http://news.bbc.co.uk"
links[9]="http://www.news.com.au"
window.location=links[myrandom]
}
</script>
Radio Button
<form>
<input type="button" value="random link!" onClick="randomlinks()">
</form>
How do I remove the radio button "form" and move the functionality of into a "a href" attribute. The a "a href" link will be used in a simple nav bar.
I don't like to put JS directly in an anchor's href attribute, I guess due to old habits of providing a valid URL in the href so that the user still gets a working page even if they've disabled JavaScript, and putting the JS in an onclick attribute.
Actually I don't really like to include inline event attributes either, but the following will work:
<a href="#" onclick="randomlinks(); return false;>Random Link!</a>
(The return false; prevents default link behaviour.)

I am doing the following:
<a href="www.stackoverflow.com">
<button disabled="disabled" >ABC</button>
</a>
This works good but I get a HTML5 validation error that says "Element 'button' must not be nested within element 'a button'.
Can anyone give me advice on what I should do?
No, it isn't valid HTML5 according to the HTML5 Spec Document from W3C:
Content model: Transparent, but there must be no interactive content descendant.
The a element may be wrapped around entire paragraphs, lists, tables, and so forth, even entire sections, so long as there is no interactive content within (e.g. buttons or other links).
In other words, you can nest any elements inside an <a> except the following:
<a>
<audio> (if the controls attribute is present)
<button>
<details>
<embed>
<iframe>
<img> (if the usemap attribute is present)
<input> (if the type attribute is not in the hidden state)
<keygen>
<label>
<menu> (if the type attribute is in the toolbar state)
<object> (if the usemap attribute is present)
<select>
<textarea>
<video> (if the controls attribute is present)
If you are trying to have a button that links to somewhere, wrap that button inside a <form> tag as such:
<form style="display: inline" action="http://example.com/" method="get">
<button>Visit Website</button>
</form>
However, if your <button> tag is styled using CSS and doesn't look like the system's widget... Do yourself a favor, create a new class for your <a> tag and style it the same way.
If you're using Bootstrap 3, this works quite well
Primary link
Link
I've just jumped into the same issue and I solved it substituting 'button' tag to 'span' tag. In my case I'm using bootstrap. This is how it looks like:
<a href="#register">
<span class="btn btn-default btn-lg">
Subscribe
</span>
</a>
No.
The following solution relies on JavaScript.
<button type="button" onclick="location.href='http://www.stackoverflow.com'">ABC</button>
If the button is to be placed inside an existing <form> with method="post", then ensure the button has the attribute type="button" otherwise the button will submit the POST operation. In this way you can have a <form> that contains a mixture of GET and POST operation buttons.
It would be really weird if that was valid, and I would expect it to be invalid. What should it mean to have one clickable element inside of another clickable element? Which is it -- a button, or a link?
These days even if the spec doesn't allow it, it "seems" to still work to embed the button within a <a href...><button ...></a> tag, FWIW...
Another option is to use the onclick attribute of the button:
<button disabled="disabled" onClick="location.href='www.stackoverflow.com'" >ABC</button>
This works, however, the user won't see the link displayed on hover as they would if it were inside the element.
You can add a class to the button and put some script redirecting it.
I do it this way:
<button class='buttonClass'>button name</button>
<script>
$(".buttonClass').click(function(){
window.location.href = "http://stackoverflow.com";
});
</script>
why not..you can also embeded picture on button as well
<FORM method = "POST" action = "https://stackoverflow.com">
<button type="submit" name="Submit">
<img src="img/Att_hack.png" alt="Text">
</button>
</FORM>
Explanation and working solution here:
Howto: div with onclick inside another div with onclick javascript
by executing this script in your inner click handler:
if (!e) var e = window.event;
e.cancelBubble = true;
if (e.stopPropagation) e.stopPropagation();
It is illegal in HTML5 to embed a button element inside a link.
Better to use CSS on the default and :active (pressed) states:
body{background-color:#F0F0F0} /* JUST TO MAKE THE BORDER STAND OUT */
a.Button{padding:.1em .4em;color:#0000D0;background-color:#E0E0E0;font:normal 80% sans-serif;font-weight:700;border:2px #606060 solid;text-decoration:none}
a.Button:not(:active){border-left-color:#FFFFFF;border-top-color:#FFFFFF}
a.Button:active{border-right-color:#FFFFFF;border-bottom-color:#FFFFFF}
<p><a class="Button" href="www.stackoverflow.com">Click me<a>
Use formaction attribute inside the button
PS! It only works if your button type="submit"
<button type="submit" formaction="www.youraddress.com">Submit</button>

Use formaction attribute inside the button
PS! It only works if your button type="submit"
<button type="submit" formaction="www.youraddress.com">Submit</button>
I'm trying to click specific button but with no result yet.
Using Python 3.4.2 and Ghost.py.
<a class="button" title="" ref="1" id="details" href="javascript:void(0);">
</a>
This code is under many div's and li's.
The simplest answer is welcomed!
You can evaluate a line of Javascript with Ghost.py and use the click method on the appropriate DOM element you get with getElementById:
page, resources = ghost.evaluate("document.getElementById('details').click();", expect_loading=True)
UPDATE
To get the link by class use the following line
ghost.evaluate("document.getElementsByClassName('button')[0].click();", expect_loading=True)
There is another version you can use to select and click the first link with an ref="1" attribute on your page:
ghost.evaluate("document.querySelector('a[ref="1"]').click();", expect_loading=True)
<a href="javascript:OpenRuleEditor('#Url.Action("AddRule", "AdvancedRuleSearch", new { mode = "add" })','AddNewRule','Add New Rule')" style="text-decoration: none; display:inline-block">
<input name="Plus" type="image" src="~/GHAimages/129.png" id="btnAddRule" title="Add New Rule"/>
</a>
By Clicking this Button it will open a new page. Button is basically a image button (Iconic which helps user to understand what they are doing exactly). Working fine in Firefox and Chrome. But in IE 11 it is not working. when I am changing its type from type="image" to type="button", it starts working, but it is not showing the image.
Also have tried with the following code, by putting it inside tag.
onclick="window.location=this.parentNode.href;
Now, Image is showing on the button, button is working also and page is also opening but in the back side the window from which it has been invoked.
Any help is welcome..
You can use an <img> tag instead of an input tag.
<a href="javascript:OpenRuleEditor('#Url.Action("AddRule", "AdvancedRuleSearch", new { mode = "add" })','AddNewRule','Add New Rule')" style="text-decoration: none; display:inline-block">
<img src="~/GHAimages/129.png"></img>
</a>
Also, I don't think you need a tilde in your path, try replacing src="~/GHAimages/129.png" with src="/GHAimages/129.png". I would try this before using the image tag.
There is no valid reason to wrap an <a href> tag around an input[type="image"].
Have you considered just using an <img>?
In a page I'm working on I have this HTML (simplified version; the original is a bit more complex).
<a href="alink.php" >
<b>1</b>
<span name="aName" data-editable="text" ></span>
<span class="type">numeric</span>
</a>
Then I have a system that allows an "edit mode".
That edit to mode changes that HTML to this:
<a href="alink.php" >
<b>1</b>
<span name="aName" data-editable="text" ><input name="aName" type="text"></span><img src="ok.png"><img src="x.png"></span>
<span class="type">numeric</span>
</a>
The issue is as follows:
When the user clicks the input how can I have the carret where the user clicked without anything else happening?
For that I tried this:
If I use the preventDefault(), the user is not sent to the link but the carret is also not positioned where the user clicked.
If I use stopPropagation(), nothing is prevented, the link is clicked.
If I use both, same as preventDefault() happens.
One possible solution I thought is to get rid of the <a> and replace it with a different tag, like a <span> tag. I just would prefer not to have to do that due to how this system works. If you think that there's a nice alternative, then please state it.
No examples or answers with libraries please
Edit: My relevant js code, as requested:
this.editableElement = document.createElement('input');
this.editableElement.type = "text";
this.editableElement.onclick = function (e){
e.preventDefault();
e.stopPropagation();
}.bind(this);
this.editableElement.name = this.parent.getAttribute('name');
this.editableElement.value = this.currentText;
Edit2: jsfiddle as requested.

Now try to place the caret where you clicked. You'll check that the input becomes selected, the link is not followed but the caret is not placed where you clicked.
