JavaScript - Linking A Single Img To Multiple Onchange Events
Hi,
First time here. I have had no luck searching on Google or here regarding this. Any help is appreciated. 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: Thank You! Code: function dropdownimageMidC()
{
if(!document.images)
return
if(document.standard5.Mid_Connector.options=="Mid-no connector"){
if(document.standard5.Mid_Separate.options=="Mid-do not separate"){
document.images.schematicMid.src="image/std_mid_H.png";
}
if(document.standard5.Mid_Separate.options=="Mid-separate"){
document.images.schematicMid.src="image/std_mid_slit_H.png";
}
}
if(document.standard5.Mid_Connector.options=="Mid-connector"){
if(document.standard5.Mid_Separate.options=="Mid-do not separate"){
document.images.schematicMid.src="image/std_mid_connector_H.png";
}
if(document.standard5.Mid_Separate.options=="Mid-separate"){
document.images.schematicMid.src="image/std_mid_slit_connector_H.png";
}
}
}
Code: function dropdownimageMidS()
{
if(!document.images)
return
if(document.standard5.Mid_Separate.options=="Mid-do not separate"){
if(document.standard5.Mid_Connector.options=="Mid-no connector"){
document.images.schematicMid.src="image/std_mid_H.png";
}
if(document.standard5.Mid_Connector.options=="Mid-connector"){
document.images.schematicMid.src="image/std_mid_connector_H.png";
}
}
if(document.standard5.Mid_Separate.options=="Mid-separate"){
if(document.standard5.Mid_Connector.options=="Mid-no connector"){
document.images.schematicMid.src="image/std_mid_slit_H.png";
}
if(document.standard5.Mid_Connector.options=="Mid-connector"){
document.images.schematicMid.src="image/std_mid_slit_connector_H.png";
}
}
}
Similar TutorialsI'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. Code: <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. How would i add more scripts like the above? Hello. I'm new to JavaScript to any help in understanding would be great. For an html form, i'm am trying to have it so when a user clicks on the 'email' input box then a div element next to it displays "please make sure it's correct", and when they click out of the box (ie, to the next field), the message disappears again. I have managed to make it appear using this; Code: function displaymessage()
{
document.getElementById("message").innerHTML="please make sure your email address isn't fake.. you dick";
}
<input class="textbox" name="email" onclick="displaymessage()"<input type='<p id="message"></p>
BUT, how do i make it disappear when the user clicks out.. is it onchange()?.. if so, how. many thanks!! Can we have two onFocus javascriptscript events for single HTML Tag? Thank you..
I have created my website and i have one page that has a spry menu bar with 15 columns. I also have a javascript file that is an image gallery. i want to add that javascript file to my html/css website. not only that but i need that java script file to open on the appropriate image depending on what titled column i have clicked on. any help would be greatly appreciated!
Hi all, I'm new to javascript and am having a few issues. I have a function that I want to run with multiple onchange events. My page has several image selection buttons and I want it to preview the image when/if each one is selected. I have gotten it working for the first on the page but cannot for the remainder. Is this possible or am I wishful thinking?

If you simply want to assign multiple listeners for the same event on a single element, use element.addEventListener("change", eventHandler) instead of element.onchange = eventHandler or <element onchange="eventHandler();"></element>. The simplified code below works, and should give you an idea of what Im trying to achieve. The final version will have dozens of input fields so you can see why the below method stinks Code: <html><head><title>Values</title>
<script type="text/javascript">
<!--
function getid() {
var myNum = document.frm1.field1.value;
if(myNum == "A"){
document.frm1.field2.value = "1"
} else if(myNum == "B"){
document.frm1.field2.value = "2"
} else {
document.frm1.field2.value = ""
}
var myNum2 = document.frm1.field3.value;
if(myNum2 == "A"){
document.frm1.field4.value = "1"
} else if(myNum2 == "B"){
document.frm1.field4.value = "2"
} else {
document.frm1.field4.value = ""
}
}
//-->
</script>
</head><body>
<form name="frm1" id="frm1">
<input type="text" size="40" name="field1" id="field1" onChange="JavaScript:getid();" /><input type="text" size="4" id="field2" name="field2" /> <br>
<input type="text" size="40" name="field3" id="field3" onChange="JavaScript:getid();" /><input type="text" size="4" id="field4" name="field4" /> <br>
</form>
</body>
</html>
Each text input will have A or B written in by the user, which should automatically place that letters associated ID in its partner field. If any other letter is entered the ID will automatically be left blank. With the above code I'd need to repeat it over and over for each of the dozens of input fields. The final version wont be using simply A/B either but around 50 possible inputs each with their own ID which would make around 1000 possible variations. What am I missing here that will simplify the process? Thanks Hi, i got a webpage that links to 4 diffrent scripts but only one work at a time Any simple way around this ? I am looking for a way to add multiple items with a single URL to my shopping cart. any ideas? cheers, I'm having a problem with one of my Labs and My TA is not answering emails. I need to make a button, that when you click it, turns the bgColor blue, when you click it twice, it turns bgColor yellow, and a third time turns it orange. The tricky part is, I need to use an internal CSS style sheet for the color, and a function for the javascript. Here is what I have so far, but I'm completely stuck. Code: <html>
<head>
<style type="text/css" media="all">
highlight {background-color:yellow;}
</style>
<script type="text/javascript">
function blue()
{
document.bgcolor = blue;
}
</script>
</head>
<body>
<p>Good morning. In less than an hour, aircraft from here will join others from around the world..... </p>
<input type="button" value="Push me to change color!" onclick="document.bgColor= 'blue'">
</body>
</html>
(I cut out the doctype for readability) Obviously I'm not utilizing the function.. I tried replacing 'blue' with blue() (which is the name of the function) but that didn't work.. So how I utilize both the function, and the CSS sheet, AND get the button to do consecutive actions onClick..? -Thanks, this is my first post, I hope everything is understandable. Hi, When designing a web page, you may come across a situation where you want to combine content from multiple websites in a single window. Could the "iframe" tag makes this possible? If so, as it will separate your page design into several sections and display a different website in each one? Your answers are much appreciated. Thank you for watching me. Stickers I am using a freebie script that changes css elements using onClick when you hit a button. I have 12 choices I want to add, and don't want 12 buttons, but rather a dropdown list. 2 button examples (and js code) is: <input onclick="changecss('li','background','url(images/list_02.jpg) no-repeat 10.2em .12em')" value="Change to BG 2" type="button" /> <input onclick="changecss('li','background','url(images/list_03.jpg) no-repeat 10.2em .12em')" value="Change to BG 3" type="button" /> How do I convert this to a SELECT list?? Thank you! I have this script which is set to generate random anagrams of my name in rotation which works fine, but I can't work out how to put multiple instances of it on one page. if someone could point me in the right direction i'd be very grateful. thanks the code is var quotations = new Array() quotations[0]= "germaine arnold" quotations[1]= "endearing moral" quotations[2]= "analog reminder" quotations[3]= "regained normal" quotations[4]= "renaming ordeal" quotations[5]= "nominal regrade" quotations[6]= "arraigned lemon" quotations[7]= "ringleader moan" quotations[8]= "mineral groaned" function display() { a=Math.floor(Math.random()*quotations.length) document.getElementById('quotation').innerHTML=quotations[a] setTimeout("display()",5000) } and i'm calling the function using: <div id="quotation"> <SCRIPT type="text/javascript">display()</SCRIPT> </div> Hi guys. I am a newbie here on this forum. I have tried to learn how to use javascript on HTML forms however I just couldn't find the answers to my questions on the net. Perhaps I am not using the correct 'terms' when searching so I decided to join a forum like this to ask help. Anyway, I have a form with multiple inputboxes and lists and my goal is to generate and display all the accumulated information to a textarea so that the user can copy it afterwards. I have an idea how I could make it work but I am not entirely sure how to put it on a code. I actually have a number of questions on this so let me start off with the first one. I am eager to learn javascript so I would post my questions one after the other as my questions get answered. That way I get to learn how to build the code from the top. So my first one is this.. 1. I would like to know how to display a user input on an inputbox to a textarea. My html form is like this: Code: <html>
<head>
<script language="javascript">
function generateLogs (form)
{
TW_Logger.tickDoc.value = TW_Logger.name.value;
}
</script>
</head>
<body>
<form name="TW_Logger">
<label for="name_id">Name: </label>
<input type="text" name="name" id="name_id"/><br /><br />
<label for="logs_id">Ticket Documentation: </label><br />
<textarea cols="53" rows="5" name="tickDoc" id="tickDoc_id">
</textarea><br /><br />
<label></label>
<input type="submit" value="Generate Logs" class="button1" onclick="generateLogs(this.form) " />
</form>
</body>
</html>
I don't know what I did wrong but the script is not working. I appreciate any help I can get from anyone. Thanks! This may seem a bit of an unusual question, but I've been tossing around an idea in my head for an experimental collaborative art & music website. I've not started building the site at all, and I've only a little HTML and no scripting experience. I plan on most likely using a service like squarespace for the ease of updating and member system and other features. (I imagine a few around here scoff at that kind of service! But that's beside the present issue.) So I imagine that if javascript is capable of handling this, it's not an extremely complicated solution. For example: say I have a song I'd like users to be able to listen to, but I want to split the parts (drums, strings, guitars, vocals, etc.) among a few different audio files, all embedded within close proximity of each other (say arranged vertically in two columns) on the same page. I want this so that users are free to play around with the parts, dropping them, lowering & raising volume, even pulling them out of sync if they please. Now what I want is a single button that will trigger all of the audio files to begin playback simultaneously, say, above the embedded files and centered. Would this be possible? Could anyone offer assistance in setting up this kind of thing? Thanks in advance! Hi Everyone! I have a website that I'm designing where I have the need to search multiple sites at specific times. By this I mean that In some cases, we would want to search only the internet using google, or only search the site that I've created (which currently uses the jse_search.js solution), or only our company's website. I currently have four different search boxes that will search either the internet, the internal site, a separate internal site, or a third-party website, which all working fine. The problem is that the search boxes take up quite a bit of space, and the layout is becoming cumbersome. Is there a way in Javascript I could use a single search box and a drop-down list to select which method to use? The code I'm currently using is below. With the exception of the Google search function, I've modified some of the site names to general site names and paths to preserve the company's anonymity: Code in the <head> tag: Code: <script language="JavaScript1.3" type="text/javascript" src="jse_form.js"> </script> Code in the <body> tag: Code: <!--Begin Internal Site Search 1!-->

i have a link that references: <a href="My_Video.asx">video</a>. when you click, video will open in the "windows media player" and the parent window goes blank. how can i prevent the parent window from going blank? thank you for help julio This is what I have: http://page-test.co.uk/js-test.html ..and it works exactly how I want it to, but I need it to work by doing these two things: (a) If you see in the change_button function, I have hard coded the 'name_can_vary' name element. I need to do it so this isn't hard coded (so it can work on any page/form). (b) I don't want to change any of the HTML, and I only want to change the code used in the change_button function (otherwise I will need to change many pages). Thanks in advance. hello, Im trying to write a program when the user clicks on the button, the textbox should display "how are you ". This is what I tried : <html> <head> <title>"Click"</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head> <body> <p> <input name="text1" type="text" id="text1" value="textbox 1" onFocus="this.style.background ='yellow'" onBlur="this.style.background='white'"> </p> <p> <input name="text2" type="text" id="text2" value="textbox 2" onFocus="this.style.background = 'yellow'" onBlur="this.style.background='white'"> </p> <p> <button onclick="textbox1.value="how are you">Click Me!</button> </p> </body> </html> i have placed a text box with onclick and onblur event. onclick shows contents(links) of a div tag below it and onblur hides the div basically it was a jquery based drop down menu but due to some problem I need to avoid jquery. Now the problem happens when a link of div tag is clicked. The link does not work due to onblur event on the textbox. Any suggestion? Quote: <input type="text" style="text-transform: capitalize;" value="" class="abd_txtfld" name="loc" id="loc" onclick="gettabcontentSearch('','')" onblur="hide()"/> <div id="cityddsearch" class="select_citydd" style="position: absolute; margin-top: 2px; left: 5px; display: none;"> <ul> <li><a href='../link1.asp'>link1</a></li> <li><a href='../link2.asp'>link2</a></li> <li><a href='../link3.asp'>link3</a></li> </ul> </div> Hi Guys I have been trying to implement a way of using `onclick` to fill out a form field, with a Value assigned by a clickable rollover image. So i have a image rollover of a PC, i give the PC a Value? ID? of `PC No34` When the image is clicked it updates its Value of PC No34 to a Form text field which is named `pcid` the Form is on the same page as the PC rollover image. I have been trying most of the day but not getting it. Pls help Thanks for any help with this Willo |
