JavaScript - Double Click Value In A Listbox
hello
I have a listbox full of names on a PHP website and was wondering if there was a way to grab the value during a double click to bring me to another form to display the name and information? Similar TutorialsOk know those people who are in the bad habit of double clicking everything? Well my site breaks if they double click it... is there a script I can use that won't let my functions run more then once every so many seconds? to avoid double clicking errors? I've been working with this script Code: function changeImage(layer_id, item_id, position) {
var theDiv = document.getElementById(layer_id);
var theImg = (theDiv != null) ? theDiv.firstChild : null;
if (theImg != null) {
// If the item id is 0, then just make the image empty lol
if (item_id == 0)
{
theDiv.parentNode.removeChild(theDiv)
} else {
theImg.setAttribute('src', 'images/' + layer_id + '-' + item_id + '.png');
}
} else {
var toAppend = '<div id="' + layer_id + '" style="position: absolute; z-index: ' + position + ';"><img src="images/' + layer_id + '-' + item_id + '.png" /></div>';
document.getElementById("item-images").innerHTML += toAppend;
}
}
where layer_id, item_id, and position are all defined elsewhere. I've been trying to get the images to append, and then run this line Code: theDiv.parentNode.removeChild(theDiv) when you click on them consecutively(click to append, click again to remove, so three consecutive clicks would have the image shown and four would not), but all I've succeeded at so far is breaking the script's functionality. Help? Hi All, I have webform ,in that we have written some javascript for validation .we are calling this validatation while saving the form by using on client click event .Now we want to prevent the double time clicking the button .I have rounded the entire net but none of the code is not working because we have already calling the on client click function .I tried by calling 2 functions in on client click .But no use.Please suggeset some thing differnt and easy approach Awaiting for the reply Hi, I have an application wherein for one page I want to display a Listbox on selection of a radio button. There should be 2 radio buttons and when the user clicks on the 2nd one "My Process", a list box should be displayed with several options. Can anybody pls help me with this as I'm a beginner to JS.. Many thanks Pooja. I'm probably not allowed to request something like this, but since this is a small amount of code I think I should do it anyways :P Okey, so I have two listboxes and I want a tickbox to enable one listbox and disable one listbox as you tick a checkbox. I want one listbox disabled by default and the other enabled and then vice-verca the disable when you tick the box. If someone could supply me with that code I would be really greatful, butyou don't need to bother with the HTML, I should figure it out from the JS. Thanks in advance <3 I am trying to populate a listbox using Javascript. The listbox is populated using the xml response from ajax request. Below is the code used for the same Code: var xmlDoc = xmlhttp.responseXML;
for (var i = 0; i < xmlDoc.getElementsByTagName("id").length; i++) {
traderlists.add(new Option(xmlDoc.getElementsByTagName("name")[i].childNodes[0].nodeValue, xmlDoc.getElementsByTagName("id")[i].childNodes[0].nodeValue));
}
This works fine for me. But i am facing performance issue here. some ajax requests retrieves xmls with around 11,000 nodes and this takes too much of time to populate the listbox. Can anyone please advice me with an better solution? Hi, Iam trying a simple fill listbox on the body load, but its not working.

Essentially, I have an ASP.net page where I load a record set server side and upload it into a listbox. I'm trying to do all the movement functionalities of the listbox items client side. Specifically, I'm trying to figure out how to copy selected listbox items from one listbox to another -- on button click. I've searched for a while, but every example that I found moves the actual item into another listbox, I just want to copy the selected item to another listbox. I'm very new to JavaScript, so ff someone can provide an example or pseudo code, I would greatly appreciate it. Hi, I've been working on a company directory page where a listbox called "People" in a form called "people_form" contains 400 employee names. I made the box "multiple" just so I could have it big and easier to find names but I decided a search box would be really useful. I've looked up a few such search scripts but so far the two I've tried haven't worked. The latest one when it's installed on the page, nothing happens when you type characters into it (it's supposed to jump to an entry matching the first few letters). Although if I backspace then it selects EVERY name in the list Here's the current form with the input tag being the search box (oh the options are populated by java script): <form name="people_form"> <input type="text" id="realtxt" onkeyup="searchSel()"></input> <select onchange="display(this.value); return false;" multiple="multiple" id="People" name="People" style="border-style: none; height:198px; width:220px;"> <option value="">Loading</option> </select></form> And here's the actual search function in the head of the page in the script tags: function searchSel() { var input=document.getElementById('realtxt').value.toLowerCase(); var output=document.getElementById('People').options; for(var i=0;i<output.length;i++) { if(output[i].value.indexOf(input)==0){ output[i].selected=true; } if(document.forms[0].realtxt.value==''){ output[0].selected=true; } } } If you know of a script that will work properly I'd appreciate it. For convenience I'm looking for one that jumps to selections inside the listbox as opposed to one where you click a search button and get results somewhere else. Hi I've been working on a listbox full of employees for our company intranet. Each name has an onchange tag that calls up a floor map and that part works fine but I'd really like to populate the names from an XML list so it's easier for non-IT people to maintain. I've been doing alot of web searches on the subject which comes up alot but it's mostly just fragments of what I need being that I've got no javascript background. I found a helpful tutorial on javascriptkit but that wasn't for creating listboxes so I'm only part of the way there. This is the XML file I've got (there will eventually be 400 entries): <?xml version="1.0"?> <list> <employee> <name>##########</name> <office>1656</office> <officePH>(403)000-0000</officePH> <mobile>N/A</mobile> <email>##########</email> </employee> <employee> <name>#########</name> <office>1657</office> <officePH>(403)000-0000</officePH> <mobile>N/A</mobile> <email>###########</email> </employee> </list> The most important parts are the name which will be used as the text of the box and the office number which will determine which floorplan is displayed. I added the other information so I can potentially put it in a div display later but that can wait. Can anyone help point me to some good resources on this subject? Thanks. Hi there, I have a listbox and an Edit button. The user will need to click on the email address in the listbox before clicking on the button to edit. But then, the email address will be displayed on the prompt box's textbox, and even without editing it, the user can get scot-free. I would want to remove the email address on the prompt box's textbox, and also to check for null entries. If it is null, it will display an alert message. Else, it will check if it is a valid email address. My code is as follow: Code: function editItem()
{
var listbox = document.getElementById('listBox'); // listbox control id
var newValue = lst.value;
if(newValue != "")
{
var newItem = prompt("Enter the new email address",newValue);
if(newItem == "")
{
alert("Please key in an email address into the textbox.");
return false;
}
else
{
listbox.options[listbox.selectedIndex] = new Option(newItem,newItem,false,false);
return false;
arrTexts = new Array();
validRegExp =/^\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,3}$/
// search email text for regular exp matches
if (arrTexts.value.search(validRegExp) ==-1 )
{
alert('A valid e-mail address is required.\nPlease try again.');
return false;
}
else
{
for(i=0; i<listbox.length; i++)
{
arrTexts[i] = lst.options[i].text;
}
arrTexts.sort();
for(i=0; i<listbox.length; i++)
{
listbox.options[i].text = arrTexts[i];
listbox.options[i].value = arrTexts[i];
}
}
}
}
else
{
alert('Select Item From The List To Edit ');
}
}

var arrayX=[];
function getValue(){
var x=document.getElementById("combo_color");
for (var i = 0; i < x.options.length; i++) {
if(x[i].value!=''){
arrayX.push(x[i].value);
}
}
}
for example, with the color Green Karanka I only get Green inside the array, the same happens with any color with more than one word, any ideas? Thanks. Hi there, I would like to do the following: When I click on a button, it will set the item in the listbox to be bold. But this will only happen when the user clicks on the desired item to be bold and presses the button. An alert message will occur when he/she presses the button without clicking on the item, stating that the user will need to click on the item. How shoukld I do it in javascript? Hi there, I have this listbox that I want the user to select only one choice at a time.

Please advise me on the problem. if i have a large script built multi-select-list-box, is there a way within javascript to onClick of a hyperlink, jump-to the line within the select box that corresponds to the value clicked?
I have a page with three identical listbox containing items in the same order. When an element is selected from any of the three lists, the script should search for the occurrence of the same element in other two lists and remove them on the fly from all the three lists. How can this be achieved? A script to achieve this is welcomed. I am creating a recipe cookbook program. On the main page, I have a top frame (named "nav") and bottom frame (named "recipe_layout"). There is a listbox in the BOTTOM frame containing the recipe names, and a "View Recipe" button in the TOP frame. The user would select a recipe and then click the button to view the recipe in the bottom frame. I believe that I need to insert the code to make this work with the button (?), and I think my problem is that I'm not accessing the bottom frame correctly: CURRENT CODE FOR LISTBOX IN BOTTOM FRAME <form name="recipe_form" style="margin-top:30"> <select name="name_dropdown" multiple size="2"> <option selected="selected">Search byName</option> <option value="applepie.html">Apple Pie</option> CURRENT CODE FOR BUTTON IN TOP FRAME <input type="button" value="View Recipe" onclick="parent.recipe_layout.location.href='recipe_form.name_dropdown.options[selectedIndex].value'"> Thank you so much in advance!! <!-- ** Need help completing the javascript in this example ** --> Code: <html> <head> <title>Convert ListBox data into 4 Text Boxes</title> <script language="javascript"> function SplitText ( // NEED HELP WITH THIS CODE split text ","; convert to ['textbox1','textbox2','textbox3','textbox4'] } </script> </head> <body> <form name="convert"> <p style="margin: 2px"> <h3>Convert selected data to textboxes</h3> <!-- SELECT DATA FROM LIST BOX --> <select size="1" name="ListBox" onChange="SplitText();"> <option value="jim,bob,rick,paul" >==Row1==</option> <option value="pete,jack,chris,craig">==Row2==</option> <option value="mary,jane,lisa,kim" >==Row3==</option> </select> </p> <h3>In this example say we selected row1</h3> <!-- THE SELECTED DATA GETS SPLIT AND INSERTED INTO THESE 4 TEXTBOXES --> <p style="margin: 2px"> <input type="text" name="textbox1" value="jim"><br> <input type="text" name="textbox2" value="bob"><br> <input type="text" name="textbox3" value="rick"><br> <input type="text" name="textbox4" value="paul"><br> </p> </form> </body> </html> |
