JavaScript - How To Get Text Input To Be Used As A Reference To An Image Src
I've been looking for a reference to my situation for two days and i can't find any that are relevant enough.
I'm trying to accept text as a URL for an image source. I then display that image in a form with the use of a <button type=button onclick=codeThatGeneratesImage > type thing. Code: function addImageToForm(formID) {
//get a reference to the form
var formElement = document.getElementById(formID);
//get a reference to the element that contains the url
var elementWithImageURL = document.getElementbyId("imageURLInput");
//get URL entered
var imageURL = elementWithImageURL.getAttribute("value");
//create image element
----------------------------------------------------------------------------------
var newImage = document.createElement("img");
//reference the source using the url
newImage.setAttribute("src", imageURL);
newImage.setAttribute("name", "newImage");
//append the image to form
formElement.appendChild(newImage);
}
i know that the bottom half works because i tried it with just a reference to an image directly and it worked. i can't figure out why most of the top part isnt working. any help would be much appreciated Similar TutorialsHi I'm trying to write a data checking function that after it completes should return the focus to the text box that was checked and highlight everything in it IF the value was unacceptable. Here is the function: Code: <script type="text/javascript">
function chkValidity(numToCheck)
{
if (isNaN(numToCheck) == true || numToCheck < 0)
{
alert("Please enter a number greater than zero");
numToCheck.focus()
numToCheck.select()
return false
}
}
</script>
And here are the lines of code that would call the function: Code: <input type="text" name="numBedrooms" size="3" maxlength="3" onblur="return chkValidity(this)" /> <input type="text" name="areaBedrooms" size="3" maxlength="3" onblur="return chkValidity(this)" /> <input type="text" name="numLivAreas" size="2" maxlength="3" onblur="return chkValidity(this)" /> <input type="text" name="areaLivAreas" size="3" maxlength="3" onblur="return chkValidity(this)" /> <input type="text" name="numServAreas" size="2" maxlength="3" onblur="return chkValidity(this)" /> <input type="text" name="areaServArea" size="3" maxlength="3" onblur="return chkValidity(this)" /> What I find happens is that the data checking works and the error mesage displays, but the focus does not return to the text box. Any ideas? Regards Jenny I am running some javascript code which generates a popup window associated with a spell checking program. The way the program works, is that it takes the text out of a text field (passed as an object), spell checks the string, then puts it back into the text area field. My text area is located within a flash form, and I am having trouble pointing to it. I am sure my spell checking program is working, as it works fine if I point to an html text area. Do I have to do something special to point to a flash form object? Here is my code: Code: <!--- Source the JavaScript spellChecker object --->
<script language="javascript" type="text/javascript" src="../Spellchecking/spellerpages-0.5.1/speller/spellChecker.js">
</script>
<!--- Call a function like this to handle the spell check command --->
<script language="javascript" type="text/javascript">
function openSpellChecker() {
// get the textarea we're going to check
<!--- pointer to text area --->
var txt = window.activity.Summary;
// give the spellChecker object a reference to our textarea
// pass any number of text objects as arguments to the constructor:
var speller = new spellChecker( txt );
// kick it off
speller.openChecker();
}
</script>
Also, here is my text area: Code: <cfform format="flash" id="activity1" height="#formheight#" width="100%" style="#formstyle#" timeout="3600" wmode="transparent" name="activity" onLoad="#initVars#; onFormLoad();">
<cftextarea name="Summary" id="Summary" html="yes" maxlength="1000" tooltip="Summarize your entry here. The field has a 1000 character limit. This summary is included in the generated End of the Week reports." onChange="submitTemporary('Summary', Summary.text);requiredContent('summary');" onFocus="if(detailsBox.height>60){detailsBox.height=60;summaryBox.height=220;}"></cftextarea>
</cfform>
Any help on this issue would be much appreciated. Thanks, AeroNicko Hi all can someone guide me (total JS newbie) on this presumably pretty easy task? I have a "parent" page with some text inputs in it (a form). This is what I am after: -when the user clicks a link it pops open a new window via JS - "child" (this is working). -in the "child" window there are also some text inputs (another form) (done). -when the user changes the value for 'testChild_textInput_4' in the child window, then I want it to automatically set this same value, to effectively overwrite, what is currently in 'testParent_textInput_2' in the parent window. Presumably this involves an onChange event, but it is also OK with me if the needful (the text input's value in the parent window being overwritten) happens upon the child window's form submit. If anyone can show me either trick, I would be thrilled! I set up a test page to make this all easy to talk about: http://www.yellow-turtle.com/testDumpMe_parent.html Please let me know! Thanks! -John I am thinking this should be fairly easy but yet I am not getting far. I want to have a form with a single text imput field for a zip code. Depending on which zip code the user enters will determine which url they will be sent to. If they enter a zip code which is not in the script, they would be sent to a default url. I am also assuming this can be accomplished with javascript. Any help is greatly appreciated. well title says it all i have a search form, and the default value is "enter text here" when the user click the submit button, i would like to check if the value of my text input is "enter text here" and if it is, then don't submit the form (popup a warning or something) how can i do that? thanks a lot! hi friends , i am on make a dynamic input field creation code , my problem is the entered text(value from "add proposition") is washing away , if i press new "add proposition" my java script is PHP Code: <script language="javascript" type="text/javascript"> function add() { k=document.getElementById("num").innerHTML k=parseInt(k); if(!k) {document.getElementById("num").innerHTML=1; k=1;} else{ document.getElementById("num").innerHTML=k+1; k++; } document.getElementById("cat").innerHTML+="<br />type propositon "+(k)+":<input type=\"text\" name=\"prop"+k+"\">is it answer? <input type=\"checkbox\" name=\"ans"+k+"\"> ignore this one:<input type=\"checkbox\" name=\"ign"+k+"\">" } </script> my html code is PHP Code: <form action="new.php" method="post"> <fieldset> <legend>Add Question & answer:</legend> question type:<br /> True or False:<input type="radio" name="radio" value="t"> Objective:<input type="radio" name="radio" value="o"> Other:<input type="radio" name="radio" value="o"> Quesion:<br /> <textarea name="desc" rows="6" cols="35" ></textarea> <br /> <a href="javascript:add()" ><b>add proposition</b></a> <div id="cat"></div> <div id="num" style="display:none;"></div> <br> <input type="submit" name="submit"> </fieldset> </form> how i solve this problem ? hi folks, i needed a text input so the user that will register a product, will make sure to enter the cents, and not just the raw money, making it to be stored incorrectly on my database. for example, if i type "1" the output inside the text field will be automatically "0.01", so the user HAS to type the cents. thanks in advance Currently I have several forms using the input text "field3". I want to know how I can require an HTML input text field to be required WITHOUT having to use the form name in the javascript and without modifying <body>,<form> or <input type="submit">. Also no HTML5 since not all browsers use it (life would be simple if they did since threres a required tag) So here is my form, for example Code: <form name = "test"> <input type="text" name="field1"> <input type="text" name="field2"> <input type="text" name="field3"> <input type="submit"> </form> In otherwords, I can only edit <input type="text" name="field3"> by putting code directly before, in, or after that input field. With this problem, how can I make it required? thank you hi i wants to change one input to texarea when i select one from radio, plz any suggestion how i would do that? my code PHP Code: <input type="text" name="other" value="this need to become textarea" /> <input type="radio" name="inputtext" />Text <input type="radio" name="inputtext" />Textarea so when i click inputtext radio name"other" will become a textrea rather then input type text. thanks for any help. Hi, I have a form with text boxes which I need to display values ie. <input type="text" name="image_ref" value="image1" /> This works no porblem until I enter the below javscript onto the page: <script type="text/javascript"> var level1 = document.getElementById('level1'); level1.style.display = 'none'; var level2 = document.getElementById('level2'); level2.style.display = 'none'; var all_levels = document.getElementById('all_levels'); all_levels.style.display = 'none'; </script> This code is to hide certain parts of the form until they are activated. the problem is when the parts of the form are activated and displayed, the values inthe text input boxes do not show. Any ideas why this is? many thanks in advance. Sorry, not sure if I need Javascript for this so I posted it in the html forum as well I'm looking to create a simple page where a user can copy and paste a list of ingredients and then push a button to search that list for a number of key words. Key words: Amodimethicone, Trimethylsilylamodimethicone, Glycerin, Trideceth-12, Behenoxy, Bisamino, Aminoethyl, PG-Propyl, Phenylpropyl, Methicone, Cyclomethicone, Cyclopentasiloxane, Cyclohexasiloxane, Cyclopentasiloxane, Dimethiconol, Trimethylsiloxysilicate, Silicate, Siloxy, Trimethylolpropane, Diisostearoyl, Copolyol, Dodecylbenzenesulphonate, Diphenyl, silicone, Methicone, Simethicone, Trisiloxane, sulfate, Myreth, Lauryl, Laureth, Sulfonate, dodecylbenzenesulfonate, Xylenesulfonate, Ammonium, Isethionate, Sulfoacetate, Sarcosinate, Sulfosuccinate, Carboxylate, Taurate, glycinate I don't care how they are alerted if any of the key words match their ingredients pop up, highlight, whatever. *Incase anyone is wondering it is to search hair products for any form of silcones or sulfates since many people wish to avoid them but they come in many different forms. Thanks!! I have a very small script that simply displays a search box and redirects a user to a URL if they enter 29401 or 29455, else they go to a default page. The script works fine, but I cannot figure out how to make value="enter a zip code" in the input box so that it disappears when you click in the box. I also can't get the form to submit by pressing enter, you have to click "check". I can get all this working in straight HTML but the same won't work w/ javascript. Any help please? <SCRIPT LANGUAGE="JavaScript"> function zipValidate(){ val = document.zipForm.zip.value; switch(val){ case "29401": case "29455": document.location = 'http://www.gohere.com'; break; default: document.location = 'http://www.or-go-here.com'; break; } } </SCRIPT> <form name="zipForm" id="zipForm" method="post" action=""> <input name="zip" type="text" id="zip" maxlength="5" /> <input name="zipButton" type="button" id="zipButton" value="Check" onclick="zipValidate()" /> </form> Hi all, I am working with a php code that I am trying to edit a bit. The last part I am trying to change I cannot figure out. Essentially I want to change the "Login" submit button to just a text link that says "Login" instead. Quote: <form action="<?php echo JRoute::_( 'index.php', true, $params->get('usesecure')); ?>" method="post" name="login" id="form-login" > <?php echo $params->get('pretext'); ?> <input id="modlgn_username" type="text" name="username" class="inputbox" alt="username" size="15" value="<?php echo JText::_('Username') ?>" onclick="login.username.value='';" /> <input id="modlgn_passwd" type="password" name="passwd" class="inputbox" size="15" alt="password" value="<?php echo JText::_('Password') ?>" onclick="login.passwd.value='';" /> <?php if(JPluginHelper::isEnabled('system', 'remember')) : ?> <label for="modlgn_remember"><?php echo JText::_('Remember me') ?></label> <input id="modlgn_remember" type="checkbox" name="remember" class="inputbox" value="yes" alt="Remember Me" /> <?php endif; ?> <input type="submit" name="Submit" class="button" value="<?php echo JText::_('LOGIN') ?>" /> <?php I am hoping this is just a minor change. Would someone mind showing me what I have to do? Thanks very much. Hi, I'm trying to display a time clock in input text box. The time should display in Time utilization box after clicking on START BUTTON. I tried the below code and it is not starting the time. However, I tried the javascript individually and it worked. Any help? PHP Code: <script type="text/javascript"> var seconds = 0; var minutes = 0; var hours = 0; function zeroPad(time) { var numZeropad = time + ''; while(numZeropad.length < 2) { numZeropad = "0" + numZeropad; } return numZeropad; } function countSecs() { seconds++; if (seconds > 59) { minutes++; seconds = 0; } if (minutes > 59) { hours++ minutes = 0; } document.getElementById("time_utilization").innerHTML = zeroPad(hours) + ":" + zeroPad(minutes) + ":" + zeroPad(seconds); } function startTimer() { action = window.setInterval(countSecs,1000); } </script> </head> <body> <?php include("header.php"); ?> <div class="art-content-layout"> <div class="art-content-layout-row"> <div class="art-layout-cell art-content"> <div class="art-post"> <div class="art-post-body"> <div class="art-post-inner art-article"> <form name="tracker" method="post" action="processor.php" onsubmit="return formCheck(this);"> <ul> <li class="mainForm" id="fieldBox_8"> <label class="formFieldQuestion">Start Time *</label><input readonly class=mainForm type=text name=start_time id=start_time size='30' value=''> <input type="button" id="start1_time" style="width: 100px" Value="Start Time" onClick="startTimer()"></li> <li class="mainForm" id="fieldBox_12"> <label class="formFieldQuestion">Time Utilization</label><input class=mainForm type=text name="time_utilization" id="time_utilization" size='8' value='00:00:00' ></li> <br /> <br /> <li class="mainForm"> <input id="saveForm" class="mainForm" type="submit" value="Submit" style="width : 100px"/> </li> </form> I am getting "Unknown Runtime Error at line 43".

Hey everyone, I've looked around quite a bit and can't seem to find anything but I was wondering if there is some open source software offering a text editor/input field similar to the one used on this forum when submitting a comment or thread? Where you can click a bold button or Italic button or URL button to structure it? Thanks Josh Hello everybody I have a page where I have several input text fields (the number of fields is variable), the input text fields are disable , only the first one is enable, as the user goes filling out the text fields, the next text field becomes available, each time the user fills out an input text field, the form is submitted. As I said, the number of text fields is variable, some times I have only one and other time I can have 7. I would like to create a javaScript function to put the next available text field ready to star writing, without having to click in the text field first. The id of my form is "reports" , the id of the table is,"run_params" and the id of my input texts is "inputp". I am using JSF, the HTML output generated for each field is id="reports:run_params:1:input" , the number 1 indicated that is the first input text, this number can go from 1 to 20. I have tried to create a code where I can read how many input fields I have and then create a loop that checks all of them and search for the field that is enable and empty, and put that field on focus. But so far my code doesn't work. I don't have too much experience with javaScript and I already have tried many different ideas, without success, I have not idea how to achieve this objective, because I don't know very well javascript's capabilities, so I don't know what it is possible and what it is not. Any help????!!! Thanks in advance I'm building a template editor and need some help changing some of the variables. Part 1. Only at DEALERNAME. Must present coupon at time of write-up. Cannot be combined with any other offer. 1 coupon per customer per transaction. Expires: 00/00/00.s I need to be able to fill out two fields to change DEALERNAME and 00/00/00. I found a way to do this but it required the output to be in a field. I need it the output to look no different than before. Part 2. I'm using this to change some text via radio button but I would like an option to select how many details are there is the first place. Say they only want 1 or 2 details and not 3. Head Code: <script language="javascript" type="text/javascript">
function detail1a(){
document.getElementById("detail1").innerHTML = "Up to 5 Quarts";
}
function detail1b(){
document.getElementById("detail1").innerHTML = "Synthetic Oil Extra";
}
function detail1c(){
document.getElementById("detail1").innerHTML = "Lube Chassis";
}
function detail2a(){
document.getElementById("detail2").innerHTML = "Up to 5 Quarts";
}
function detail2b(){
document.getElementById("detail2").innerHTML = "Synthetic Oil Extra";
}
function detail2c(){
document.getElementById("detail2").innerHTML = "Lube Chassis";
}
function detail3a(){
document.getElementById("detail3").innerHTML = "Up to 5 Quarts";
}
function detail3b(){
document.getElementById("detail3").innerHTML = "Synthetic Oil Extra";
}
function detail3c(){
document.getElementById("detail3").innerHTML = "Lube Chassis";
}
</script>
Body Code: <span style="font-weight: bold;">Offer Details</span><br /> <p style="margin: 8px 10px"> Detail 1<br /> <input type="radio" name="on/off" onclick="detail1a();" />Up to 5 quarts<br /> <input type="radio" name="on/off" onclick="detail1b();" />Synthetic Oil Extra<br /> <input type="radio" name="on/off" onclick="detail1c();" />Lube Chassis<br /> </p> <p style="margin: 8px 10px"> Detail 2<br /> <input type="radio" name="on/off" onclick="detail2a();" />Up to 5 quarts<br /> <input type="radio" name="on/off" onclick="detail2b();" />Synthetic Oil Extra<br /> <input type="radio" name="on/off" onclick="detail2c();" />Lube Chassis<br /> </p> <p style="margin: 8px 10px"> Detail 3<br /> <input type="radio" name="on/off" onclick="detail3a();" />Up to 5 quarts<br /> <input type="radio" name="on/off" onclick="detail3b();" />Synthetic Oil Extra<br /> <input type="radio" name="on/off" onclick="detail3c();" />Lube Chassis<br /> </p> Output Code: <ul> <li><span id="detail1">Detail 1</span></li> <li><span id="detail2">Detail 2</span></li> <li><span id="detail3">Detail 3</span></li> </ul> This is hopefully a simple fix and I hope someone can help me out, I'm pretty new at coding. I have a form on an html page and I want to make it so when a button is clicked, it adds one to the input to the right of it, and when a button to the right of the input is clicked, it will delete one to the left of that button. I don't want to resort to making a new function for each and every form, because there will be a lot. Here is the form and input parts: Code: <form name="calculate"> <input type="button" onClick="add()" /> <input name="result" type="input" readonly="readonly" value="0" /> <input type="button" onclick="sub()" /> </form> Here is what the function code looks like: Code: function add()
{
var add = 1 * calculate.name.value;
add = add + 1;
calculate.name.value = add;
}
function sub()
{
var add = 1 * calculate.name.value;
add = add - 1;
calculate.name.value = add;
}
Note: where I called the calculate.name.value, that obviously doesn't work, and I need some way, rather than making multiple functions and changing the name part, to be able to call to a name near the button, if at all possible. Any and all ideas are appreciated, Thanks! Hi, I'm currently programming a menu editing script and I'm trying to reorder value of text input on change. What I'm trying to do is when I change the value of a text box it reorders the others. EX Start 1 2 3 4 5 Change 3->1 End 2 3 1 4 5 Here is what I've manage to do, it works only when the number is bigger. Javascript function Code: function changeOrder(current)
{
var num_name = current.name.split("_",2);
var id = num_name[0]+"_"+num_name[1]+"_number";
var maxorder = document.getElementById(id).value;
var currentmax = current.name.substr((current.name.length-1),1)
if(currentmax <= maxorder && current.value > 0)
{
var start = (currentmax > current.value ? 1 : currentmax);
for(var i=start;i<maxorder;i++)
{
var k = parseInt(i)+1;
x = document.getElementsByName(num_name[0]+"_"+num_name[1]+"_order_"+k);
x[0].value = i;
x[0].name = x[0].name.substr(0,(x[0].name.length-1))+i;
}
current.name = current.name.substr(0,(current.name.length-1))+current.value;
}
}
HTML input Code: <input type="text" style="width: 20px;" onchange="changeOrder(this);" value="1" name="other_title_order_1"> Thanks for any advices you may have Maxetime I tried to create a new text input once the last text box gets focus.
