Multiple Onload Events - Doesn't InitThree Overwrite The Previous?
Apr 24, 2010
It's from this article here and it appears to be a classic script that's wildly used. [URL]
[Code]...
It makes sense that initOne & InitTwo get called at the same time.. but why doesn't initThree overwrite the previous? And it's strange to me that oldOnload(); is initOne the first time arround. the second time it's == to the functions it's now contained in.
I am new to Javascript and am trying to add some functionality to a website but have come across a problem when trying to utilise two seperate Javascript onloads events. I have a text scroller to display the latest news and I also have a javascript lightbox gallery. Both of these events work perfectly on their own but when I try to include both on one page only one of the events is executed. My code is displayed below:
I am creating a form in which a checkbox is checked based on the info from previous page.The info I am passing is the client ID (which is a number I can pass in the URL variable)In the form I have a list of clients (with checkboxes next to them)Now if you come from a specific client page the checkbox with the client name should be already checked since you are getting info regarding that client, with the option of selecting other clients.So any idea on how I can accomplish this using Javascript?
How would I write 2 onload events into the body tag?
I currently use:
onLoad="if (self != top) top.location=self.location" and have found a scroller that may work better than my current one but it has an onload command as well.
I am working on my website and I have it coded to rotate my header banner from one to the other at onload but I would like to run a running scroll in my task bar also. I know both the rotating headers and scrolling called the function from the body tag at on load. Individually they both work but not together.
I have been reading and practicing Javascript for the last month and so far I'm happy with it. I noticed that you can add Event Listeners and trigger a function based on that event but I also noticed that you could add an event directly to any element as an attribute, something like:
Code: <p onclick="doSomething()">Click Me</p> function doSomething(){ //do something }
So my question is why would someone add and event listener instead of adding that event directly in the element (as the sample above)? The reason I'm asking is because adding event listeners involves more code: Code: var elementName= document.getElementById('elemenstsID'); elementName.addEventListener("click", doSomething, false);
I guess what I don't know understand is why would someone choose to add an event listener instead, I know it is more OOP but doesn't the "onclick","onload" etc., do the same thing?
I have a dinky ajaxSubmit plugin which causes a form submit action to submit that form via AJAX along w/ some validation. Currently, in a global.js file which is included by every page, I have:
Sort of a global onload event. The plugin uses the live() method to bind so that future forms added via any callbacks would be wired up as well. Question is: is this a best practice w/ jQuery? Is there a better way to wire up plug-ins for DOM events w/o using this sorta global onload event?
This code block occurs several times. Sometime the first div ist just "inner" and the second div is missing.
Now I need to update the "new" DIV based on the height of the previous inner-new DIV. For one it works fine:
var height = $('#inner-new').outerHeight(); $('#new').css('margin-top', height*(-1)-30);
But how could I re-use this universally for all my boxes. It needs to check if the DIV "box" contains the DIV "inner-new" as first element, if that is true it need to update the DIV "new".
I tried several things with $('#box').each(function(i) { ... }); but couldn't come up with a solution.
I have an frame in one of my documents (not a frameset document). The top level document has an "onload" handler in the BODY tag. I have found that if the frame is unable to navigate to the document it desires, the top level document "onload" handler does not fire, and therefore important Javascript function I need called is not called.
The frame document's URL belongs to a service which is not always available, and when it isn't available, a 404 error results in the frame and ends up neutering the top level document body onload handler.
I can deal with the 404 error, but is there some way to ensure that the top level document's body onload handler fires?
I'd like to switch any broken images in dynamically loaded HTML to a warning graphic, something like:
[Code]...
This works with with the 'click' event but not with 'error' or 'load'is there another way to do it? I remember with .live() there were restrictions on what events could be bound, but I can't find that in the documentation anymore for jQuery 1.7's .on()
If I set this variable:var divExsist=document.getElementById(bindDivID);and the DIV in question doesn't exist, will it return a NULL that I can use in an if statement?I'm trying to put a safety in my function so that if the Div is already there, it won't overwrite it.
Does anyone know of a good tutorial that shows an example of a Javascript function listening for more than one events? Such as listening to multiple events?
All the examples that I have been able to find were ones that listen to only one event.
I have several pages, each having a button and a textbox. The button has an onclick event directly coded into the HTML markup.The textbox has a onchange event in a similar fashion.What I need to do is create a small javascript snippet which adds another function to the onclick event of the button, and the onchange event of the textbox.I am not allowed to make any changes to the HTML of the pages, or the functions which are called originally by the events.All I can do is place a small javascript file in the head section of the pages.
The code should attach another function which is called during the event, while at the same time preserving the current function attached to the event.
Any solution in javascript to activate overwrite mode on input fields (not using the keyboard)? I found a solution on this forum but this didn't work on FF.
I am working on a simple control panel where I have text input fields in which a user can click on a text box and the text will automatically focus and select. I have done this fine. However, when I use the same onclick event for multiple fields, only the last one created works. So, if I were to comment out the password and email field additions, then the userName field would work correctly. If I were to just comment out the email field, password would work correctly but userName would not. And finally, if I have the code as is, userName and password do not function correctly while email does.
I've done extensive searching, but each example or explanation I come across is too different from my own, so it's ultimately no use. The problem is that I barely know anything when it comes to Javascript, but yet I'm trying to use it. I have a form on a page. This form contains 6 <select> elements, each with its own <option>Other</option> element. If something isn't listed, the user can choose "Other" and then type into a textbox which appears.
I have the following code, which works great if only applied to one <select> element. <select name="How did you hear about us?" id="How did you hear about us?" onchange="makeBox1()"> <option value="0" selected="selected">-- Select --</option> <option value="1">Search Engine</option> <option value="2">Referral</option> <option value="3">Trade Publication</option> <option value="4">Vendor Web Site</option> <option value="5">Your Company Website</option> <option value="6">Direct Mail</option> <option value="7">Other</option> </select><div id = "inputBox1"></div> <script type = "text/javascript"> function makeBox1() { var a = "<input type = 'text' name = 'box1' id = 'box1' class='form popup'>" if (document.getElementById("How did you hear about us?").value==7) { document.getElementById("inputBox1").innerHTML = a; } else { document.getElementById("inputBox1").innerHTML = ""; }} </script>
I've read that you have to combine onchange events, but I have no idea how to do this (I've done plenty of trial and error, trying to make every item unique, but to no avail.
JavaScript is not my strong point though and I have found that the previous web editor has a lot of repeat functions on the pages.
My idea is to create an external .js file and just call the function...it is for a rotating banner ad. The problem is the the function is called in the <Body> tag..this means that I have to change 100's of pages by adding the call function to the tag on every page.
Is there a way I can call the function as well as adding the function to the onLoad event.
I have tried adding "window.onload = rotateBanner;" to the beginning of my javaScript but it does not seem to work...what am I doing wrong
