I want to dynamically add a set of fields to a table when when the user onBlur the selection drop-down. I want the cursor to be in the text field of the newly added set. I have been playing around with onfocus function on the hyperlink to see if when focus is gained, it would throw the user into the text field. I am getting the impress that the field has not been created yet, so the getElementbById function cannot find the object just recently created.

I'm new to the forums but discovered this site while looking for a solution to my javascript problem. I was able to find/manipulate the following code for changing a banner when a person mouse-overs a button. It is almost exactly what I want it to do, except that I'd like the following functionality to be added to it: 1) When a person hovers over a button, the image that appears should be clickable and open a webpage. 2) I would like to have the banners cycle/rotate by default until a person hovers over a button. When they hover, it should stop the cycle/rotation. Here is an example of what the code produces prior to my desired tweaks above: http://javascript.internet.com/image...e-gallery.html Here is the code I currently have: Code: <html> <head> <script language="JavaScript"> function update(url,index,isSuper) { document['PhotoBig'].src=url; } </script> </head> <body> <div style="margin-left: 30%;"> <table cellpadding="0" cellspacing="0" border="0" width="234"> <tr> <td colspan="8"><img src="images/hipaa-logo.png" name="PhotoBig"></td> </tr> <tr> <td colspan="8"><img src="images/w_spacer.gif" width="1" height="5"></td> </tr> <tr> <td width="120"> </td> <td width="24"><a onMouseOver="update('images/alz-logo.png', 0, false); return false;"><img src="images/button1.png"></a></td> <td width="21"><a onMouseOver="update('images/ecomm-logo.png', 1, true); return false;"><img src="images/button2.png"></a></td> <td width="21"><a onMouseOver="update('images/facebook-logo.png', 2, true); return false;"><img src="images/button3.png"></a></td> <td width="21"><a onMouseOver="update('images/hipaa-logo.png', 3, true); return false;"><img src="images/button4.png"></a></td> <td width="27"><a onMouseOver="update('images/swain-logo.png', 4, true); return false;"><img src="images/button5.png"></a></td> </tr> </table> </div> </body> </html> Any suggestions would be GREATLY appreciated! Thanks! jstwondrng Hi all, I have table in Javascript and it has addrow, deleterow, submit, and functions. when i click it automatically adds new row and it has select option to choose some of them for ex. in added two rows and one of drop down combox i chose Motherboard Asus and from other i chose Motherboard Gigabyte.

Code: function UpdateCanvas (CanvId) { var canvIDNames = ["front", "back"]; // DOM IDs var currentCanvas = document.getElementById(canvIDNames[CanvId]).getContext("2d"); var newImg = ""; var topLeft = CanvId * 63; var bottomRight = topLeft + 63; var xa = 0; var posX = 0; var posY = 0; var imgCode = ""; for (xa = topLeft; xa < bottomRight; xa++) { newImg = new Image(); imgCode = regRead(xa, 1); newImg.src = getBase64src(imgCode); newImg.onload = function () { currentCanvas.drawImage(newImg, posX, posY); if (posX == 400) { posX = 0; posY += 90; } else { posX += 50; } } } } I am very very new to programming and trying to create a web interface for a model. The user needs to be able to add as many compounds as they want and add a variable number of subgroups for each compound. Also, each input needs a distinct name. I have tried adapting someone else code to add/remove form inputs but am not having any luck creating subgroups. below is my code Code: <html> <head> <title>form</title> <content="text/html"; /> <script type="text/javascript"> <!-- window.onload = function () { if (self.init) init(); } var counter = 0; var counter1 = 0; function init() { document.getElementById('moreFields').onclick = moreFields; document.getElementById('moreFields1').onclick = moreFields1; moreFields(); moreFields1(); } function moreFields() { counter++; var newFields = document.getElementById('readcomp').cloneNode(true); newFields.id = ''; newFields.style.display = 'block'; var newField = newFields.childNodes; for (var i=0;i<newField.length;i++) { var theName = newField[i].name if (theName) newField[i].name = theName + counter; } var insertHere = document.getElementById('writecomp'); insertHere.parentNode.insertBefore(newFields,insertHere); } function moreFields1() { counter1++; var newFields = document.getElementById('readsubgr').cloneNode(true); newFields.id = ''; newFields.style.display = 'block'; var newField = newFields.childNodes; for (var i=0;i<newField.length;i++) { var theName = newField[i].name if (theName) newField[i].name = theName + counter1; } var insertHere = document.getElementById('writesubgr'); insertHere.parentNode.insertBefore(newFields,insertHere); } // --> </script> </head> <body> <div id="readcomp" style="display: none"> Comp name<input type=text name="comp" value="" size="2"/> Concentration<input type=text name="comp_qty" value="" size="2"/> <input type="button" value="Remove comp" onclick="this.parentNode.parentNode.removeChild(this.parentNode);" /><br/> <span id="writesubgr"></span> <input type="button" id="moreFields1" value="add subgroup" /><br/><br/> </div> <div id="readsubgr" style="display: none"> Subgroup Name<input type=text name="subgroup" value="" size="2"/> Quantity <input type=text name="subgroup_qty" value="" size="2"/> <input type="button" value="Remove subgroup" onclick="this.parentNode.parentNode.removeChild(this.parentNode);" /><br /> </div> <form action="cgi_bin\show_input.pl" method="post"> <span id="writecomp"></span> <input type="button" id="moreFields" value="add comp" /><br/><br/> <input value="Run Program" type="submit"> <input value="Reset all fields" type="reset"> </form> </body></html> any help would be appreciated. thanks Hi, I have a dynamic JS table and the user can add several rows then populate rows with data. There are 4 columns in table. First row, first two columns have JQuery calendar. Third column has populated select list. Fourth column, first row has JS function to ensure that user enters integer/decimal with corresponding alert for incorrect entry. Two things I want to do: 1. Populate added rows with JQuery calendars and integer/decimal alert. 2. Capture added rows and data from user entries so that information can be sent to database via ColdFusion programming. The following is the js code I am using: For the datepicker I linked to an in-house URL so this is the function - Code: $(function() { $("#startdate").datepicker(); $("#enddate").datepicker(); $("#RcompStart").datepicker(); $("#RcompEnd").datepicker(); }); </script> The objects (inputs) for the above are Code: <td><input style="width: 70px" type="text" id="startdate"></td> <td><input style="width: 70px" type="text" id="enddate"></td> For the numeric alert the function is Code: <script type="text/javascript"> function checkQuarters( fld ) { var val = parseFloat(fld.value); if ( isNaN(val) || ( val*4 != Math.floor(val*4) ) ) { alert("Value must be a numeric and a multiple of 0.25"); return false; } return true; } </script> The object (input) for the above is Code: <td><p> <form style="width: 5px; height: 1px;"> <input type="text" name="No. of Hours" id="No. of Hours" style="width: 70px;" onblur="checkQuarters(this);" /> </form> </td> And to add and remove rows the function is Code: <script language="Javascript" type="text/javascript"> /*<![CDATA[*/ var new_rows=new Array(); var row_count=0; function addRow() { var tbl = document.getElementById('ReqDtTbl'); new_rows[row_count]=new Array(); var lastRow = tbl.rows.length; var iteration = lastRow; if (lastRow>7){ return;} var row = tbl.insertRow(lastRow); var cellLeft = row.insertCell(0); var textNode = document.createElement('input'); textNode.size = 7; textNode.name = 'startdate' + iteration; cellLeft.appendChild(textNode); new_rows[row_count]['cell']=textNode; var cellRight = row.insertCell(1); var el = document.createElement('input'); el.type = 'text'; el.name = 'enddate' + iteration; el.id = 'enddate' + iteration; el.size = 7; new_rows[row_count]['cell2']=el; cellRight.appendChild(el); // the last cell! var cellRightSel = row.insertCell(2); var sel = document.createElement('select'); sel.name = 'TypeHrs' + iteration; sel.options[0] = new Option('-Select-', '""'); sel.options[1] = new Option('Comp Time', 'Comp Time'); sel.options[2] = new Option('Credit Hrs', 'Credit Hrs'); sel.options[3] = new Option('Overtime', 'Overtime'); sel.options[4] = new Option('Rel Comp', 'Rel Comp'); cellRightSel.appendChild(sel); new_rows[row_count]['cell3']=sel; var cellRight = row.insertCell(3); var el = document.createElement('input'); el.type = 'text'; el.name = 'No. of Hours' + iteration; el.id = 'No. of Hours' + iteration; el.size = 7; cellRight.appendChild(el); new_rows[row_count]['cell']=el; row_count++; } function removeRow() { // grab element again var tbl = document.getElementById('ReqDtTbl'); // grab length var lastRow = tbl.rows.length; // delete last row if there is more than one row if (lastRow > 2) tbl.deleteRow(lastRow - 1); } /*]]>*/ </script> The buttons for this function are Code: <input type="button" value="Add a row" onclick="addRow('ReqDtTbl',5)";/> <input type="button" value="Remove a row" onclick="removeRow();" /> That's it. Thanks - John Below, I added: bmiresult to my database but I get the error: There has been an error: could not prepare statement (1 table bmical has no column named bmiresult) Code: html5rocks.webdb.createTable = function() { var db = html5rocks.webdb.db; db.transaction(function(tx) { tx.executeSql("CREATE TABLE IF NOT EXISTS bmical(ID INTEGER PRIMARY KEY ASC, height1 INTEGER, weight1 INTEGER, added_on DATETIME, bmiresult INTEGER)", []); }); } html5rocks.webdb.addTodo = function(todoText) { var db = html5rocks.webdb.db; db.transaction(function(tx){ var weight1 = document.getElementById("weight1").value; var height2 = todoText / 100 var BMI = weight1 / (height2 * height2) var BMI = BMI; var bmiresult = BMI.toFixed(3); var addedOn = new Date(); tx.executeSql("INSERT INTO bmical(height1, weight1, added_on, bmiresult) VALUES (?,?,?,?)", [todoText, weight1, addedOn, bmiresult], html5rocks.webdb.onSuccess, html5rocks.webdb.onError); }); } I'm trying to add the ui autocomplete function to some form fields using a facebook style, but I'm not sure how to get more than one value to actually pass to the form field. As my script is now it only takes the last selected value into the hidden form field. Here's my current script: Code: <div id="editcbprofileinterests"> <div id="formWrap"> <div id="interests" class="ui-helper-clearfix"> <input id="cb_intereststerm" type="text"> <input id="cb_interests" name="cb_interests" type="hidden"> </div> </div></div> <script type="text/javascript" src="autocomplete/js/jquery-1.4.2.min.js"></script> <script type="text/javascript" src="autocomplete/js/jquery-ui-1.8.custom.min.js"></script> <script type="text/javascript"> $(function(){ //attach autocomplete $("#cb_intereststerm").autocomplete({ //define callback to format results source: function(req, add){ //pass request to server $.getJSON("autocomplete/autocominterests.php?callback=?", req, function(data) { //create array for response objects var suggestions = []; //process response $.each(data, function(i, val){ suggestions.push(val.cb_intereststerm); }); //pass array to callback add(suggestions); }); }, //define select handler select: function(event, ui) { //create formatted interest var interest = ui.item.value, span = $("<span>").text(interest), a = $("<a>").addClass("remove").attr({ href: "javascript:", title: "Remove " + interest }).text("x").appendTo(span); //add interest to interests div span.insertBefore("#cb_intereststerm"); //add interest to hidden form field $('input[name=cb_interests]').val(interest); }, //define select handler change: function() { //prevent 'to' field being updated and correct position $("#cb_intereststerm").val("").css("top", 2); } }); //add click handler to activities div $("#interests").click(function(){ //focus 'to' field $("#cb_intereststerm").focus(); }); //add live handler for clicks on remove links $(".remove", document.getElementById("interest")).live("click", function(){ //remove current activity $(this).parent().remove(); //correct 'to' field position if($("#interests span").length === 0) { $("#cb_intereststerm").css("top", 0); } }); }); </script> Hi, I would like to prevent the addition of duplicate items in the following situation. Firstly, I have a listbox with a few options such as Code: <select id="listbox" name="listbox" multiple="multiple" style="width: 580px;"> <option>Java</option> <option>PHP</option> <option>Perl</option> <option>Javascript</option> <option>C#</option> <option>Powershell</option> </select> Next, I have a submit button with a textbox. The user will be able to submit new options into the listbox via the textbox and submit button. Therefore, I need to prevent the user from entering duplicate items into the listbox. How should I do? The following code is used to add items into the listbox. Code: function addItem() { var lst = document.getElementById('listbox'); // listbox control id var newItem = prompt("Enter New Item","Enter Value Here"); //Option object is created for every option in a selection //new Option([text[, value[, defaultSelected[, selected]]]]) // Syntax if(newItem == null) { return false; } else { lst.options[lst.length] = new Option(newItem,newItem,false,false); return false; } } Hi everyone, now I need to add items into a dropdown list, and the items would be sorted alphabetically and it does not allow duplicate items to be added. Can anyone help take a look and see what's wrong with my code? Javascript Code: function addAnotherOption() { var newItem = document.getElementById("Text44"); if (!newItem.value == "") { var answer = confirm ("Are you sure you want to add? ") if (answer)//if answer is true { var lst = document.getElementById('comboBox'); // listbox control id // Now we need to create a new 'option' tag to add to MyListbox var newOption = document.createElement("option"); newOption.value = newItem.value; // The value that this option will have newOption.innerHTML = newItem.value; // The displayed text inside of the <option> tags for (var i = 0; i < lst.options.length; i++) { arrTexts = lst.options[i].text; if (arrTexts.toLowerCase() == newItem.toLowerCase()) { alert ("That option is already included in the list - please enter another item."); return false; } else { // Finally, add the new option to the listbox lst.appendChild(newOption); //sort items in listbox in alpha order arrTexts = new Array(); for(i=0; i<lst.length; i++) { arrTexts[i] = lst.options[i].text; } arrTexts.sort(); for(i=0; i<lst.length; i++) { lst.options[i].text = arrTexts[i]; lst.options[i].value = arrTexts[i]; } } } } } else { if(newItem.value == "") { alert("Key something to textbox please."); } else alert("Cancelled."); } } HTML Code: <input id="Text44" type="text" /> <input id="Submit22" type="submit" value="Add" onclick="addAnotherOption()" /><br /> <select name="combo" id= "comboBox" style="width: 323px"> <option value="H">Hearts</option> <option value="D">Diamonds</option> <option value="C">Clubs</option> <option value="S">Spades</option> </select> I'm stuck! - I have a search form, that when data is entered and submitted, the data is sent to another page! - this works well see eg below. http://www.nctfleetlist.co.uk/normal.php My problem is, I have a piece of javascript called "greybox", it basically loads an external page, dimming the first page and focusing on the external - see eg below. http://www.nctfleetlist.co.uk/div4.php The new window can be called via either a href "rel" link or an "onclick" command.
