JavaScript - Deleting Rows From Table
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? Similar TutorialsMy 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? 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 I 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? 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>

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! The below javascript code only displays table rows in class ms-formlabel that contain (AP) in the text. It works great. However, I also need it to also insert a new row right above any rows that also contains (H: and in the detail of that new row, I need the string following the H: So a table row with (AP)(H:Sleepless), would insert a row right above that row as follows Code: <TR><TD>Sleepless</TD></TR> possible? Thanks for any help! Code: <script type="text/javascript">
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,"");
var row = theRows[r],
cells = row.getElementsByTagName('td');
if (cells[0].className.indexOf('ms-formlabel') > -1)
{
if (strTitle.indexOf("(AP)") == -1)
{
theRows[r].style.display = "none";
}
else
{
theRows[r].cells[0].innerHTML = theRows[r].cells[0].innerHTML.replace("(AP)","");
}
}
}catch(err){}r+=1;
}

Hi there, so i am working on a website, and on it there is a video with youtube api. I need to hide all Table-rows that are not during each 5 second time frame. So for example, when it is at 0:36, it will hide all TR's besides the TR that has to do with the video between 0:35 and 0:40. Each TR displays a start time, content, and end time. Here is what the tables currently look like. Code: <table width="600" class="table" >
<tr class="item-titles">
<td width="75" class="none">Start</td>
<td width="400">Caption</td>
<td width="75">End</td>

And you can see the page at http://134.117.226.43:8000/check_sub...ty/test101/91/ any help ? 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 I have a temp HTML file that is based the code I found on this site at http://www.codingforums.com/showthread.php?t=103961. It dynamically adds and removes rows from an HTML table with inputs in the cells. I have tweaked my copy a bit to match our needs. Of importance to this post is that column 1 is simply the row number. Unfortunately, I am unable to figure out how to re-sequence the first column if a row is deleted. For example, if there are 4 rows, and I delete row 3, I need to re-sequence (re-number) the values to reflect 1, 2, 3, not 1, 2, 4. Below is the insert logic (which adds a delete button for the row). Code: function insertRow() {
nForm = document.forms[0];
nForm['submit'].disabled = false;
nTable = document.getElementById('worksheet');
var lastRow = nTable.rows.length;
var x = nTable.insertRow(lastRow);
var a = x.insertCell(0);
var b = x.insertCell(1);
var c = x.insertCell(2);
var d = x.insertCell(3);
var e = x.insertCell(4);
var f = x.insertCell(5);
var g = x.insertCell(6);
var h = x.insertCell(7);
var i = x.insertCell(8);

Here is the logic for deleting a row (dynamically added for each row with the last line in the above code). I have added all the code after the 1st line, but it clearly does not work (but gives no errors): Code: function deleteRow(subjRow) {
subjRow.parentNode.parentNode.parentNode.removeChild(subjRow.parentNode.parentNode);
var PanelNo = document.getElementsByName('PanelNo[]');
NoRows = PanelNo.length;
if (NoRows > 0) {
var temp = new Array();
for (xx1=0; xx1 < NoRows; xx1++) {
temp[xx1] = (xx1+1);
}
// how do I do this?
document.getElementsByName('PanelNo[]').innerHTML = temp;
}
}
I have never worked with arrays like this for dynamic inputs, so any help would be appreciated. I would like to be able to write a function (or something) to count the number of rows in the table, I don't know how to do it, any help is appreciated.
have created dynamic table with two columns for ex:first column is Income column and second column is tax from Income at the third column are different percent options for ex. I wrote first column 1000 and chose from third drop down box 10% I would like when i chose 10% sum function automatically writes 10% percent of 1000 into second column so that 100 here is code if possible pls help me i really need this code and i bellieve that this code is useful both me and other users thanks beforehand here si code Code: <html><head><title>dinamik sheet</title>

I am building an elearning site where the user is taken through a series of dynamically driven pages to refine their choices. I am using php amd mysql to populate a series of tables but on the last page the table gets very long so i am trying to make the table expandable. I found this and this on http://www.javascripttoolbox.com/jquery/ and it's proving helpful but i need a little help taking it a step further. I also found this to be useful for anyone else who is trying to do the same thing: http://www.jankoatwarpspeed.com/post...nd-plugin.aspx FROM JAVASCRIPTTOOLBOX A common UI is to have a table of data rows, which when clicked on expand to show a detailed breakdown of "child" rows below the "parent" row. The only requirements a 1. Put a class of "parent" on each parent row (tr) 2. Give each parent row (tr) an id 3. Give each child row a class of "child-ID" where ID is the id of the parent tr that it belongs Original code: Code: $(function() {
$('tr.parent')
.css("cursor","pointer")
.attr("title","Click to expand/collapse")
.click(function(){
$(this).siblings('.child-'+this.id).toggle();
});
$('tr[@class^=child-]').hide().children('td');
});
This works great but my parent and child rows all contain checkboxes and If i try and check the checkboxes in the master rows the child rows associated with that master row expand and contract. I have added an extra cell to each row and i'm using a css class to add an arrow image to each master row but i am new to Javascript so i am not sure what i am doing. My code now looks like this: Code: $(document).ready(function() {
$('tr:not(.parent)').hide();
//$('tr.parent')
$('.arrow')
.css("cursor","pointer")
.attr("title","Click to expand/collapse")
.click(function(){
$(this).siblings('.child-'+this.id).toggle();
$(this).toggleClass("up");
});
});
So far the arrow image is toggling but i can't seem to work out how to get the .click function to affect the whole row and not just the image. Can anybody help me? Thanks I am trying to select multiple <tr>'s (onclick) in a <table> and then move every selected <tr> to another location in the table (on click). I will also be adding functionality to delete specific rows from a table by clicking on a <td> element, though I've already done this by doing. document.getElementById("container").deleteRow(row.parentNode.rowIndex); I am just completely unsure of how to tackle storing each selected row -- and then moving each selected row elsewhere in the table. I've seen many examples that accomplish close to what I am trying to acheive, however, they are all done via drag and drop and do not allow selecting multiple rows. hi I have just took from internet dinamic table. this table is dynamic and its rows dynamically can be increased. it sum but not like integer for ex. in row1 i enter 20 and in row2 i enter 5 it sums like 205 but i need it sums like 25 if possible pls help me Thanks beforehand here is code Code: <html>

Hey there! I found a great code to do this, but I would like to have the row defult set to hide via the Javascript. This is because I have many rows and I do not want to set them all to display:none and it would be easier and less bother to just set it in one place which is the JS code.

Hi, Have a dynamic table in JS that adds rows. Want a max of 8 rows. How can that be done? [CODE] <script language="Javascript" type="text/javascript"> function addRow() { var tbl = document.getElementById('ReqDtTbl'); var lastRow = tbl.rows.length; var iteration = lastRow; 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); var cellRight = row.insertCell(1); var el = document.createElement('input'); el.type = 'text'; el.name = 'enddate' + iteration; el.id = 'enddate' + iteration; el.size = 7; 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', 'RelComp'); cellRightSel.appendChild(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); } [CODE] John I have a table which has the number of rows depended on what the number is in the spinner. This does work e.g If I enter 25 in spinner it comes up with 25 rows, if I enter 7 in spinner comes with 7 rows. So my problem is this: What I have is a textarea where the user enters in their question and then submits the question, the question should be inserted and appear under the "Question" column. The problem is that everytime I submit a question into the table, it creates a new row. So if I had 20 empty rows in the table because I stated in the spinner I wanted 20 questions, then what happens is everytime I submit a question, it adds a new row every time, I want the question to be inserted in a current row starting from 1st row add going down 1 row every time a question is submitted. I have attached a document with this question which will show you how I want it to be displayed and what is displays currently and would hopefully explain it better for you if you are a bit confused. Code: Below is my javascript code:
function insertQuestion() {
var table = document.getElementById("qandatbl");
var tableBody = table.tBodies[0];
var textarea = document.getElementById("questionTxt");
var row = document.createElement("tr");
tableBody.appendChild(row);
var enumeratorCell = document.createElement("td");
enumeratorCell.className = "qid";
row.appendChild(enumeratorCell);
var questionCell = document.createElement("td");
questionCell.className = "question";
row.appendChild(questionCell);
var weightCell = document.createElement("td");
weightCell.className = "weight";
row.appendChild(weightCell);
var answerCell = document.createElement("td");
answerCell.className = "answer";
row.appendChild(answerCell);
var questionText = textarea.value;
var questionContent = document.createTextNode(questionText);
questionCell.appendChild(questionContent);
}
Html code of table and text area with submit button: Code: // table where questions will be inserted into
<table>
<?php
$spinnerCount = $_POST['textQuestion'];
if($spinnerCount > 0) {
for($i = 1; $i <= $spinnerCount; $i++) {?> // this get the number of questions from the spinner
<tr>
<td class="qid"><?php echo $i; ?></td>
<td class="question"></td>
<td class="weight"></td>
<td class="answer"></td>
</tr>
</table>
Code: //Text Area and submit button to submit questions <form id="enter" action="<?php echo htmlentities($_SERVER['PHP_SELF']); ?>" method="post"> <table id='middleDetails' border='1'> <tr> <th class='tblheading' colspan='2'>SESSION DETAILS</th> </tr> <tr> <td id="questionNum">Question No </td> </tr> <tr> <td id="questionContent">Question:</td> <td id="questionTextarea"><textarea rows="5" cols="40" id="questionTxt" name="questionText"></textarea></td> </tr> <tr> <td id="addQuestionRow" colspan='2'><input id="addQuestion" type="button" value="Add Question" name="addQuestionBtn" onClick="insertQuestion()" /></td> </tr> </table> </form> 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">
