JavaScript - Adding & Deleting Rows
I have created a calculator for my site but I am having troubles figuring out a way to make the "add row" and "delete row" functionality work correctly. I would like the user to only see 1 row of information and then add/delete rows as needed. I currently only have 4 static rows. If anyone can help it would be greatly appreciated. Thanks
The page is at https://learningportal.juniper.net/j...lator/Calc.htm Similar TutorialsI writed the following HTML code: Quote: <html> <head> <title>Pagina di Prova</title> <script type="text/javascript" src="/home/savio/Scrivania/prova.js"></script> </head> <body> <h1 align="center">PROVA DI RIMOZIONE DI RIGHE E CELLE DALLA TABELLA</h1> <br/><br/> <table id="nometabella" border="2" align="center" cellpadding="10%"> <tr id="nomeriga1"><td>Cella 1</td><td>Cella 2</td></tr> <tr id="nomeriga2"><td>Cella 3</td><td>Cella 4</td></tr> <tr id="nomeriga3"><td>Cella 5</td><td>Cella 6</td></tr> </table> <input type="submit" value="Enter" onclick="return del()"/> </body> </html> and the following javascript code: Quote: function del() { if (document.getElementById) { var tabella = document.getElementById("nometabella"); var riga1 = document.getElementById("nomeriga1"); tabella.removeChild(riga1); } } I want to delete first row of table, but it happens nothing. How can solve this problem? My table starts like this: Code: <table> <tr> <td rowspan='2'></td><td>Data</td><td>Data</td><td>Data</td> </tr> <tr> <td>Data</td><td>Data</td><td>Data</td> </tr> </table> When an addRows button is clicked, the first two rows are copied (cloned), a checbox is then inserted into the row1 cell1, then the two rows are appended: <table> <tr> <td rowspan='2'></td><td>Data</td><td>Data</td><td>Data</td> </tr> <tr> <td>Data</td><td>Data</td><td>Data</td> </tr> <tr> <td rowspan='2'><input type='checkbox' name='check[]'></td><td>Data</td><td>Data</td><td>Data</td> </tr> <tr> <td>Data</td><td>Data</td><td>Data</td> </tr> </table> Rows,except the first two can then be deleted by selecting the appropriate checkbox and clicking a deleteRow button. The check[] only exists after the first two rows have been copied and appended, so undefined means only two rows exist. Having a problem with the while loop. If a browser sees the next sibling of a tr as a td, the the loop should force the browser to go to the next sibling until its a tr, i.e row4. But its causing my browser(FF) to become unresponsive. Code: function deleteRow()
{
if(check == 'undefined')
{
return;
}
else
{
var check = document.getElementsByName('check[]'),row,nextRow,x;
var len = check.length;
for(x=len-1; x>=0; x--)
{
if(check[x].checked)
{
row = check[x].parentNode.parentNode;
while(row.nextSibling.nodeName != 'tr')
{
nextRow = row.nextSibling;
}
nextRow = row.nextSibling;
alert('ok');
}
}
}
}
Appreciate ans help with this? My table had the following layout. Code: <table> <tr> <td rowspan='2'><td> <td>Data</td><td>Data</td><td>Data</td> </tr> <tr> <td>Data</td><td>Data</td><td>Data</td> </tr> </table> After clicking an add rows button, the two rows are cloned and appended as follows with a checkbox added as shown. Code: <table> <td rowspan='2'><td> <td>Data</td><td>Data</td><td>Data</td> </tr> <tr> <td>Data</td><td>Data</td><td>Data</td> </tr> <tr> <td rowspan='2'><input type='checkbox' name='check'><td> <td>Data</td><td>Data</td><td>Data</td> </tr> <tr> <td>Data</td><td>Data</td><td>Data</td> </tr> </table> I want to be able to delete rows 3&4 by selecting the checkbox in row 3 and clicking a delete rows button. Regardless of how many sets of rows have been previously added, any set of rows can be deleted by selecting the appropriate checkbox(es) and clicking delete button. I'm trying to figure out how this can be done. My thinking is if checkbox is checked, calculate row index. I would then have to call deleteRow twice on that row index. Is there a better way of doing this? Hi, i'm a newbie in javascript. To make all clear of what I wanna do is, take a look at this URL: http://danecdotes.hostei.com/addproposal.html What i wanna do is when you click add more input link, you can have more rows to input more things. Note that in those <td> there's an input field in each <td> and I want those input to have their own names with increment ID (e.g like name1, name2, name3.). How can I make that possible? Thanks Hellooo. So I'm having trouble figuring out how to dynamically add another set of rows to a table when a button is clicked. The code below shows what goes into one set. When the button is clicked, it needs to create another three rows with the same format as the code below, but the variable names need to show what row they're on so I can easily call the values that have been inputed in another function that saves the information. Sooo for example the first variable, bhrs1-1 needs to become bhrs4-1 in the next set (because there's already a bhrs2-1 and bhrs3-1 in this set, which would become bhrs5-1 and bhrs6-1 in the new set). Sorry the code's so long! Help would be greatly appreciated. Thanksss!! Code: <TBODY>

I made a new thread for a problem that I solved a little after posting so I have removed the question in order to not waste anyone's time
i create cookies that contain multiple values using Jquery cookie plugin e.g, $.cookie('biz', ['foo', 'bar', 'lact'], {path: '/', expi 7}); from this url http://localhost/categories/educatio...r/universities and use a.remove('foo'); to remove the value after splitting, before removing value i count the number of value and if one remains to delete the cookie 'biz' entirely, even though i could remove the values, one always remains which cannot be remove from this url but only from http://localhost/categories i use .htaccess to rewrite the url, function of remove is : Array.prototype.remove=function(s){ var i = this.indexOf(s); if(i != -1) this.splice(i, 1); } please help How can I to delete white spaces around parameter that I to pass with HTML forms. For example, if I have 'firstname lastname ' or ' firstname lastname', exist it a builtin function in javascript to obtian 'firstname lastname'? savio Say I have a <textarea> input and I want to strip all the blank lines (lines with only whitespace). I have this regular expression, why doesn't it do anything? I've tried different variations with the flags (m and g). Code: ... var output = input.replace(/^\s*$/gm, "notworking!"); ... The very same regex works fine in my text editor (Notepad2), and I can match all empty lines. Code: LINE1
LINE4 ^(line 3 has some spaces)
should become Code: LINE1 LINE4 And when I finally do get this to work, how would I remove the empty line? Our site allows the user to specify his or her location, which is then stored in a cookie. As the user navigates from page to page on the site, this location is remembered. The user also has the option of changing their location. This calls a javascript function which sets the value of that location cookie to "". When another function sees that the value is "" of that cookie, it brings back the location selector. Then the user can start over and choose a location. Here's the problem: Let's say I'm on page 1 of the site and I choose location A. Then I navigate to page 2. On page 2, I say I want to change my location. Now the page shows me the location selector instead of saying that I am in location A. So far, so good. However, if I now navigate back to page 1, it thinks I am still in location A. the cookie was deleted for page 2, but still remembered for page 1. It isn't a cache issue; if I reload the page, page 1 will still say that I am located in location A, even though on page 2, I elected to delete that cookie (or to set its value to ""). What is a better way to delete cookie so that if I were to navigate back to a page on which I'd previously set the cookie, it will now know that the value is the new value (""), and not the value I'd originally set the first time I visited the page? THANK YOU! EDIT: Post deleted
I wrote a script that should delete all table rows at once. For loop deletes all rows except row 1 and row 3. Further clicking on the delete button, deletes row 1 and then 3. While loop ,on the first click on the delete button, also leaves rows 1 and 3 not deleted. Further clicking on the delete button, does not delete these rows. I was sure that both version of the script should delete all rows in the table at once. Could someone look at the script and tell me what is wrong? Thank you very much Code: <html>

Hi all.I found this code on a forum to confirm that the user wants to delete the record from database and that the link has not pressed accidently.But it is not deleting the record even after pressing ok.This is may be because the id is not passed properly. Can anyone tell why?Do I need to modify the javascript function?Here is my code: Code: function confirmation() {
var answer = confirm("Delete Record?")
if (!answer){
window.location = "by_hand.php";
}
else
{
window.location = "delete.php?delete=$id&action=deleteemployee";
}
}
PHP Code: <a href=# onclick='confirmation()'><img src='images/delete.png' alt='Delete' title='Delete' class='pngfix'></a> The code so far works, but the rows form horizontally rather than vertically. This is my first time working with XMLHttpRequest() so it's probably pretty sloppy. Also, when the function runs again, it creates another row above the previous row, I'll add a screen shot. http://tinyurl.com/7c7fylb - What it looks like when I've typed "bloodb" which means everything after the return if statement has ran twice Code: function findCard()
{
str = document.getElementById("cardName").value;
if (str.length<=4)
{
return;
}
xmlhttp=new XMLHttpRequest();
xmlhttp.open("GET","CardInfo/cards.xml",false);
xmlhttp.send();
xmlDoc=xmlhttp.responseXML;
var strLng = str.length;
var x = xmlDoc.getElementsByTagName("card");
var table = document.getElementById("cardDisplay")
var newRow = table.insertRow(0)
for (i=0; i {
var resaultStr = x[i].getElementsByTagName("name")[0].childNodes[0].nodeValue.slice(0,strLng)
if (str==resaultStr)
{
newRow.insertCell(0).innerHTML=x[i].getElementsByTagName("name")[0].childNodes[0].nodeValue
}
}
}
I wasn't sure if this should go in the JavaScript or PHP forum, so I decided JavaScript. I have created a site that has a form where the user can create as many rows as wanted. I really have no idea how I can then get this information to use in PHP. Here is my JavaScript function creating the rows: Code: function addDollyRow() {
numDollies++;
document.getElementById("numDollies").value = numDollies;
document.getElementById("removeDolly").disabled = false;
var dollyTable = document.getElementById('dollyTable');
var lastRow = dollyTable.rows.length;
// if there's no header row in the table, then iteration = lastRow + 1
var row = dollyTable.insertRow(numDollies);
// two blank cells
var blankCellOne = row.insertCell(0);
var blankCellTwo = row.insertCell(1);
// dolly list
var dollyListCell = row.insertCell(2);
var dollyListSel = document.createElement('select');
dollyListSel.name = 'dollyListRow[]';
dollyListSel.id = 'dollyList' + numDollies;
dollyListSel.options[0] = new Option('','-1');
dollyListSel.options[1] = new Option('Regular Duty Dolly Set - Collins-4.80 \'C\'','1');
dollyListSel.options[2] = new Option('Heavy Duty Dolly Set - Collins-5.70 \'C\'','2');
dollyListSel.options[3] = new Option('Super Duty Dolly Set - Collins-5.70 \'D\'','3');
dollyListCell.appendChild(dollyListSel);
// dolly material list
var dollyMatCell = row.insertCell(3);
var dollyMatSel = document.createElement('select');
dollyMatSel.name = 'axleMaterial' + numDollies;
dollyMatSel.id = 'axleMaterial' + numDollies;
dollyMatSel.options[0] = new Option('','-1');
dollyMatSel.options[1] = new Option('Aluminum','1');
dollyMatSel.options[2] = new Option('Steel','2');
dollyMatCell.appendChild(dollyMatSel);
// quantity text cell
var qtyCell = row.insertCell(4);
var qtyInput = document.createElement('input');
qtyInput.type = 'text';
qtyInput.name = 'dollyQuantity' + numDollies;
qtyInput.id = 'dollyQuantity' + numDollies;
qtyInput.size = 3;
qtyCell.appendChild(qtyInput);
}
I read something about naming each element something such as 'el[]' and then iterating through it on the PHP side, but that didn't make much sense to me. I have only been using PHP for a few weeks now so I'm pretty new. Thanks for the help! I've got this JavaScript code that is doing stuff to the content of <TR> rows.. but it's overselecting and I need to filter the <TR>s it selects in the bold line. var theRows = document.getElementsByTagName("TR"); var r = 0; var strTitle = ""; while (r < theRows.length) { try { strTitle = theRows[r].innerText || theRows[r].textContent; strTitle = strTitle.replace(/\n|\r|\t|\^ /g,""); if (strTitle.substring(0,1) == "(") { if (strTitle.indexOf("STAT") == -1) { theRows[r].style.display = "none"; ... continues Below is the rendered html. What I really want to do instead of if (strTitle.substring(0,1) == "(") Is only perform the operation when a row that is using class="ms- formlabel, or maybe has a FieldInternalName. I understand that strTitle is just pulling content, so how do I condition on other properties or strings within the <TR> row given my currently logic? Rendered HTML. <TR> <TD nowrap="true" valign="top" width="190px" class="ms-formlabel"><H3 class="ms-standardheader"> <nobr>1. Do you become short of breath or develop chest pain when climbing a flight of stairs?</nobr> </H3></TD> <TD valign="top" class="ms-formbody" width="400px"> <!-- FieldName="1. Do you become short of breath or develop chest pain when climbing a flight of stairs?" FieldInternalName="ShortofBreath" FieldType="SPFieldBoolean" --> <span dir="none"> Thanks for any help or information! I could use some help getting the following code to work... As is, it works fine in google chrome, but not at all in Internet Explorer 9. If I paste my code into w3schools "tryit" window, it will work great if it has less than 6 rows, any more and I get a generic "ERROR" on the screen. javascript code Code: <script type="text/javascript">

return s + (j ? i.substr(0, j) + t : "") + i.substr(j).replace(/(\d{3})(?=\d)/g, "$1" + t) + (c ? d + Math.abs(n - i).toFixed(c).slice(2) : "");

Please help if you can. Thanks Hi, have table with 5 rows. First 2 rows visible. Last 3 rows hidden - Code: <tr id="row1" style="display: none"> <tr id="row2" style="display: none"> <tr id="row3" style="display: none"> With onclick would like to make those rows visible to user - how can I do that? thank - john Hey guys, I have a table which contains a link to add rows in each row after the header. This link, when clicked, adds a row beneath the row which contained the clicked link. This part works perfectly. However the added rows each have a link to remove themselves from the table, and this is the part which isn't working properly. What's supposed to happen is that you click on a link, and then the row which contains the link you just clicked on is deleted. What's actually happening is when the "remove" links are clicked, first the row 2 rows above it is removed, then the row directly above it, then the correct row (itself) is deleted. Hope all of that makes sense! This is my script: Code: function addRowToTable(thisRow)
{
var tbl = document.getElementById('foodsTable');
addedRow = thisRow + addedRows;
var row = tbl.insertRow(addedRow);
row.id = addedRows;
addedRows = addedRows + 1;
var cellLeft = row.insertCell(0);
cellLeft.innerHTML = " + <input type='text'> <a href='JavaScript:removeRowFromTable(" + row.id + ")'>Remove</a> ";
var cellMiddle = row.insertCell(1);
cellMiddle.innerHTML = "<input type='text'>";
var cellRight = row.insertCell(2);
cellRight.innerHTML = "text here";
}
function removeRowFromTable(i)
{
var tbl = document.getElementById('foodsTable');
document.getElementById('foodsTable').deleteRow(i)
addedRows = addedRows - 1;
}
And this is my table: Code: <table width=100% id="foodsTable">
<tr bgcolor="#EEEEEE">
<td width=*><b>Food/Drink</b></td>
<td align="right" width=100><b>Purchased</b></td>
<td align="right" width=100><b>Produced</b></td>
<td width=60></td>
</tr>
<tr>
<td><a href="itemdetails.php?item=Apples" onMouseover="ddrivetip('<?php getToolTipData('Apples',$Foods); ?>')"; onMouseout="hideddrivetip()">Apples</a>
<a href="JavaScript:addRowToTable(2)">+ Add similar food</a>
<font color="#FF0000">*NEW*</font></td>
<td align="right"><input type="text" name="Apples" maxlength="10" size="10" value="<?php echo $session->foodsApplesPurc; ?>" style="text-align:right" /></td>
<td align="right"><input type="text" name="ApplesProd" maxlength="10" size="10" value="<?php echo $session->foodsApplesProd; ?>" style="text-align:right" /></td>
<td>kg/week</td>
</tr>
<!-- many more rows just like the one above /-->
</table>
I've highlighted the sections which I believe are most likely to be the source of my problems. Please ignore the PHP and mouseover/mouseout parts - I don't think they're relevant to this particular problem. I'm also not bothered at this stage by the fact that I'm not adding enough cells to the new rows - I'll fix this later. At this stage I just want to get the "remove" links to remove their own rows. Any ideas? Knowing me it's most likely a case of me making it way more complicated than it needs to be, and digging myself into a hole! I will be eternally indebted to anyone who can give me any help! Thanks in advance! |
