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.
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 would like to open a window "under" the current window (So it doesn't open on top). I think this can be achieved using the .blur function.
So something like: <a href="#" onclick="openWindow [URL];this.blur();return false;">Open website</a> (Obviously this doesn't work)
I've seen ways to do it, if I'm using 1 url, but because I have a list of 30 different links, I can't simply use: Code: <SCRIPT LANGUAGE="JavaScript"> function goNewWin() { TheNewWin =window.open("somepage.html"); TheNewWin.blur(); } </SCRIPT>
Which is why I need something that I can use on each different url individually that opens a new window under the current one.
Is it possible to add an onclick event to an iframe or perhaps a DIV that holds an iframe?
In specific I am using the Facebook Open Graph like button code...
What I would like to do is add a simple onclick event to it so that I can run a process when the user clicks on it, at the moment I am just trying alert but cannot get it to work. By setting the iframe within a DIV with height/width specs set would an onclick event work within the DIV?
I'm filling in for a coworker on a radio stations website.
The station currently streams live online. I want to add an event tracking so I can track how many people are streaming. I'm really new to js, but I think I figured it out (keyword is "think"). However, there was already an onclick event within the anchor tag. Can I have two in the same tag? Is there a better way to do this?
I have the following code which places multiple buttons on a page. I need 6 of the 7 buttons to perform two actions on one click. I have searched the web and can't quite comprehend the suggestions that I find. (I'm a newb). :confused:
Is it possible to just onClick=action1 & action2?
Here's the code. I seperated the head from the body to reduce the amount of scrolling....
I attached an onclick event to a link, however I have another one, that needs to be put on the same link, unfortunately I have no idea how to do it. how can I attach the function changecolor to the "abcdefgh" link?
dataCheck validates the inputs value and if something is wrong, then.. document.getElementById('error_anInput').innerHTML = 'Error!' or if data is valid then the content of span is removed.
The checkWholeForm function iterates through all elements on the form and triggers onblur() for each input... leading to executing function dataCheck (and so changing innerHTML of some specific span elements if needed).
*The Problem* If I have entered incorrect data to an input and hit the submit button with my mouse (causing the onBlur event to be triggered just right before onSubmit) then *occasionally* for some fields the onSubmit event is not triggered because the onClick event is not triggered. :S
As there are actually quite many complex functions (tested and these seem OK afaik) that are doing the checks then dowes anyboudy have a clue what type of code might break this. I thought at first that setting innerHTML to some value during onBlur disables all waiting events but as this is happening occasionally (on some machines) I'm in doubt...
any ideas what to check? double declaration of function/variable names? Not deleting some object after usage? ... anything?
Waiting for any ideas...
PS. http://eix.lap.ee/test/portali_js.html in the example *occasionally* third field generates the error - remove any content from the field and stright hit the submit (*with mouse* - to create onBlur and onClick at the same time).
I hope that someone can help me with this strange problem I have here. I have some script which changes a button and changes the onclick event. The strange thing is that although it is changing it. All the events have the same parameter even though my code is giving each button's onclick event it's own unique parameter.
I am reading values from a database into a table and I have it so that when the mouse is over a row the row is highlighted blue and when the mouse exits that row the row becomes white again - straight forward.
each row also has a check box with an onclick event and ultimately I would like when the checkbox is checked the row to be highlighted red and remain that colour. The problem is that the mouseover and mouseout events still fire. Is there way to disable these when the box is checked? Code:
Have an asp page that user selects a week from date picker and it returns data from sql table in a series of checkboxes for overtime availability. i.e., for the week of 10/10/2011 the checkboxes are Monday through Sunday, the user clicks the checkboxes they want to work overtime and hits a submit button. Let's assume they chose Monday and Wednesday. If they go back to this page later and pick the week of 10/10/2011 the sql table shows checked in the Monday and Wednesday checkboxes.
They can then make any changes they want, hit the submit button, and that sql record is updated with the new data. So on to the issue. For audit purposes, there is another sql table called ot_audit. What I want to do is every time one of the checkboxes is changed (pre hitting the submit button), I need a new record added to the ot_audit table. It will show a datetime stamp, who made the change, what was clicked, and if it was checked or unchecked. I'm new here and all I know is there are onChange and onClick events. Lost after that.
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 am trying to create a script that onload will attach an onclick and onchange event to all fields.I have also tried using setAttribute instead of attachEvent and it still does not work.Basically what the events do is disable a interval when an input field is selected and enable the interval when it is no longer selected.
So the active tab is set in the HTML to Individual by default.The following jQuery sets the active depending on which one is clicked.
Code:
$('ul#coverTabs > li').live('click', function() { // Clickable tabs // Removes default class applied in HTML and onClick adds 'currentTab' class
[code]....
what i want to achieve is when a user clicks a tab we call the XML document. The appropriate tab name is fetched and subsequently when a user clicks on a column under that tab the appropriate level cost data is displayed on the page.
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'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.
Im working on a ajax app and not sure what is the best way to bind events to elements (performance wise).I have a number of elements with 'click', 'focus', 'keydown' events which can be assigned though the delegate to the parent, like so:$('#parent').delegate('#child', 'click', func.....)but is it better to add a delegate to the 'document' for multiple events and use IF statement to filter for elements which should fire an event, like so:[code]Each element can be replaced with an updated version retrieved from the server.
I have a simple javascript overlay (like a lightbox) with a message that pops up. The user is meant to click a button, see the overlay thanking them for their vote, and then be redirected to the affiliate page (its a poll site) after about 3 seconds. I have everything down, except, it will either display the overlay as one of the onClick events, or it will do the timedRedirect but not both. I've tried putting the redirect before and after, and when its before it redirects, when its after, it shows the overlay. How can I do a timed redirect and show this message?
I am trying to tie the value of an image src to two onChange events. the events are drop down boxes in a form. I do have a couple of single event driven peices working so I think my logic is sound. I originally tried to do this with multiple if statements that tested both conditions/events. I have since given each event it's own function. I have no idea what i am doing wrong. the onChange events have no effect on the image display at all. The default image just stays in place. My JS knowledge is limited but it looks correct as far as I can tell. What am I missing.Here are the functions:
If you've caught a mouse event (say, onmousemove) and you're currently in the process of handling that event, is it possible for that, or another, mouse event handler to get hit again, at the same time that you're handling the previous event? Or is it guaranteed that no additional events will actually call any of your event handlers until your code returns from handling the prior event? That is, is it strictly sequential processing, or can they occur simultaneously?
