I have this piece of code where values are coming from php
<table class="table datatable-basic">
<tr>
<th>-<th>
<th>title<th>
</tr>
//forloop
<tr>
<td><input class="chk" type="checkbox" name="uid[]" id="uid" value="<?php echo $id; ?>"></td>
</tr>
<tr>
<td><?php echo "$title" ?></td>
</tr>
</table>
<button id="go">GO</buton>
So in my jQuery, I want to alert the value of the check box which is id, when I click the button 'go' and when that check box is checked. How can I do this?
You can use this selector input.chk:checked and the function $.toArray to get the selected elements as array and then execute the function map to get the values.
Finally, the function join will create an string with the values from the array separated by comma.
$('#go').on('click', function() {
var selectedValues = $('input.chk:checked').toArray().map(function(chk) {
return $(chk).val();
});
console.log(selectedValues.join());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table class="table datatable-basic">
<tr>
<th>title</th>
</tr>
<tr>
<td><input class="chk" type="checkbox" name="uid[]" id="uid" value="111"></td>
</tr>
<tr>
<td><input class="chk" type="checkbox" name="uid[]" id="uid" value="222"></td>
</tr>
<tr>
<td>Title</td>
</tr>
</table>
<button id="go">GO</buton>
There's a problem with your setup - they all have an ID of "uid". IDs must be unique.
But since they have a class you can do this:
var selectedValues = [];
$('input.chk:checked').each(function() {
selectedValues.push($(this).val());
});
The selectedValues array will contain the values of all of the selected checkboxes.
You could then join these together into a string separated by commas with join.
selectedValues.join(',');
To demonstrate the output I have omitted the PHP part from HTML. You can try the following code:
$('#go').click(function(){
var val = '';
$('.chk:checked').each(function(){
val += ', ' + $(this).val();
});
alert(val);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table class="table datatable-basic">

<th>-<th>

<tr>

</tr>

<td><input class="chk" type="checkbox" name="uid[]" id="uid" value="222"></td>

<tr>
<td>Title</td>

I have a single column html table with 20 rows, containing strings (used as tags):
<table id="table_of_tags">
<tr>
<td id="c_01" onclick="Pass_Content_Of_Cell(_param)">Tree</td>
</tr>
<tr>
<td id="c_02" onclick="Pass_Content_Of_Cell(_param)">Flower</td>
</tr>
....
</table>
The function Pass_Content_of_Cell() must pass the contents of the cells clicked and concatenate the tags in a single string of tags: "Flower;Tree;" (WHAT it does is not relevant).
The user can click randomly on any tag and in any order he likes.
Question: What exactly should I use for _param ? I tried this.value and this.text and didn't get anything useful.
Try this
onclick="Pass_Content_Of_Cell(this.innerText)"
or if you want the markup,
onclick="Pass_Content_Of_Cell(this.innerHTML)"
Try this.innerText
<table id="table_of_tags">
<tr><td id="c_01" onclick="Pass_Content_Of_Cell(this.innerText)">Tree</td><tr>
<tr><td id="c_02" onclick="Pass_Content_Of_Cell(this.innerText)">Flower</td><tr>
</table>
If your are using a loop to generate the markup, why you simply didn't do something like:
<tr><td onClick="doSomething('$param')">$param</td></tr>
I cannot imagine the list is hardcoded...
<script type="text/javascript">
function save(val1)
{
alert("you have saved Employee "+document.getElementById(val1).innerText);
}
function del(val1)
{
alert("you have deleted Employee "+document.getElementById(val1).innerText);
}

I'm not sure why this jquery is not working. What I want is pretty straightforward: selecting all check boxes under the region. Could someone help tell why it's not working?
$(function(){
$('.select_all').change(function() {
var checkthis = $(this);
var checkboxes = $(this).next('tbody').find('.region_ct');
if(checkthis.is(':checked')) {
checkboxes.attr('checked', true);
} else {
checkboxes.attr('checked', false); }
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table class="table">
<tr>
<th colspan=2>Americas</th>
</tr>
<tr>
<td colspan=2><input type="checkbox" name="region_am_all" class="select_all" value="X" /> Select All</td>
</tr>
<tbody>
<tr>
<td><input type="checkbox" class="region_ct" value="X" /> Argentina</td>
<td class="center"></td>
</tr>
<tr>
<td><input type="checkbox" class="region_ct" value="X" /> Barbados</td>
<td class="center"></td>
</tr>

There are a couple of issues there:
I would strongly recommend against intermixing tr and tbody elements. If you're going to use tbody (and you should), use it consistently. Browsers may relocate tr elements into generated tbody elements.
The element you're calling next on doesn't have a following sibling (at all, much less the one you're looking for). You have to traverse up the hierarchy to the tr (if you don't fix #1) or the tbody (if you do).
You don't use attr to set checked, you use prop; and you can use your existing checked boolean rather than if/else, giving is simply checkboxes.prop("checked", this.checked);
Example with updated tbodys, and I've added some countries in the Asia area to demonstrate that only the relevant checkboxes are checked:
$(function() {
$('.select_all').change(function() {
var checkthis = $(this);
var checkboxes = $(this).closest('tbody').next().find('.region_ct');
checkboxes.prop("checked", this.checked);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table class="table">
<tbody>
<tr>
<th colspan=2>Americas</th>
</tr>
<tr>
<td colspan=2>
<input type="checkbox" name="region_am_all" class="select_all" value="X" />Select All</td>
</tr>
</tbody>
<tbody>
<tr>
<td>
<input type="checkbox" class="region_ct" value="X" />Argentina</td>
<td class="center"></td>
</tr>
<tr>

<input type="checkbox" class="region_ct" value="X" />Barbados</td>
<td class="center"></td>

<th colspan=2>Asia</th>

<tr>
<td colspan=2>
<input type="checkbox" name="region_am_all" class="select_all" value="X" />Select All</td>

<td>
<input type="checkbox" class="region_ct" value="X" />China</td>
<td class="center"></td>
</tr>
<tr>
<td>
<input type="checkbox" class="region_ct" value="X" />Vietnam</td>
<td class="center"></td>
</tr>
</tbody>
</table>
You might also consider putting the select_all inside the same tbody with the checkboxes, so you could do away with next.
tbody isn't sibing of .select_all. You need to use .closest() to select parent of .select_all and use .find() to select .region_ct in it. Also you don't need to use if/else to check/uncheck checkbox. Only set this.checked to checked attribute of checkbox using .prop().
$('.select_all').change(function() {
$(this).closest('table').find('.region_ct').prop('checked', this.checked);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

I output a table when the user selects something. I have a button that will allow the user to append an empty table row to the end of the table but I can't seem to get it working properly.
HTML generation code in PHP:
echo<table>
"<table id='roof-component-data-table'><tbody>
<tr>
<th>Roof Component</th>
<th>Delete</th>
</tr>";tr>
<tr id="roofComponentRow" style="display: none;">
//empty row used to clone<td><input type="text" id="roof-component-name" name="roof-component-name[]" value="" <="" td=""></td>
echo</tr>
"<tr id='roofComponentRow' style='display: none;'>"; <tr id="roofComponentRow0">

$ComponentRowCounter++; <tr id="roofComponentRow4">

echo "< <td><a href="#" class="removeRoofComponentRow" onclick="removeRoofComponent("Insulation")">Delete</table>";a></td>
</tr>
echo"<input type='button' value='+' id='addRoofComponentRow' class='addRoofComponentRow'</>";tbody>
</table>
<input type="button" value="+" id="addRoofComponentRow" class="addRoofComponentRow">
This is what my table looks like:
<table>
<tbody>
<tr>
<th>Roof Component</th>
<th>Delete</th>
</tr>
<tr id="roofComponentRow" style="display: none;">
<td><input type="text" id="roof-component-name" name="roof-component-name[]" value="" <="" td=""></td>

<tr id="roofComponentRow0">

<tr id="roofComponentRow1">

<td>Delete</td>
</tr>
<tr id="roofComponentRow2">

<td>Delete</td>
</tr>
</tbody>
</table>
<input type="button" value="+" id="addRoofComponentRow" class="addRoofComponentRow">
Now when the user clicks the + button it will fire off some JS that should clone my empty row and append it to the end of the table.
Here is how I am attempting to do that:
$(function() {
var $removeIDValue = 0;
$(document.body).on('click', '.addRoofComponentRow', function () {
var $emptyRoofComponentRow = $("#roofComponentRow").clone();
$removeIDValue++
var $emptyRoofComponentRowClone = $emptyRoofComponentRow.clone();
var $newRowID = 'added_roof_component_row' + $removeIDValue;
$emptyRoofComponentRowClone.attr('id', $newRowID)
$emptyRoofComponentRowClone.children('td').last().after('<td>Delete</td>');
$('#roof-component-data-table').append($emptyRoofComponentRowClone);
$emptyRoofComponentRowClone.show();
});
});
When I click the button nothing is happening at all, I see nothing being added onto the table and I am getting no console errors at all. I also set an alert with that function to see if the function was even firing and my alert message did get displayed.
JSFiddle
Where am I going wrong here?
youre not appending it to anything
add <tbody id="roof-component-data-table">
https://jsfiddle.net/dr1g02go/5/
The function will work alright I guess, only there are three issues here:
the table that is selected cannot be selected, since the rendered table has no id. This is the biggest problem with this code.
echo "<td><input type='text' id='roof-component-name' name='roof-component-name[]' value=''</td>"; In this line the input isn't closed resulting in badly formed HTML.
In the HTML generation the delete link doesn't has escaped quotes, generating script errors.

I'm trying to have "set all" radio buttons at the bottom of my popup control so when the user has a long list of conflicts to resolve, they can just select one of the radio buttons and the option will be quickly select. However, my javascript fires, and seems to find the radio button, but fails to actually set the radio button.
I have a gridview gvErrors that is being looped though and in the second cell of each gridview row is a table with the options (tblOptions). I have tried using .attr("checked", true), .setAttribute("checked", true), and .prop("checked", true). I am receiving no errors, in the console, but the radio buttons all remain unchecked. Any help with this would be appreciated. Below is the Javascript.
<script type="text/javascript" language="javascript">
function selectAll(option) {
var grid = document.getElementById("<%=gvErrors.ClientID%>");
for (var i = 0; i < grid.rows.length; i++)
{
var row = grid.rows[i];
var table = $(row).find("tblOptions");
var radio = $(table).find("input[name*=" + option + "]:radio");
//$('td input:radiobutton', '#tblOptions').prop('checked', true);
$(radio).prop("checked", "checked");
var test = "";
}
};
</script>
<script type="text/javascript" language="javascript">
$(document).ready(function () {
//This handles the rows or colums selection
$("#<%=rdbCancelAll.ClientID%>").click(function() {
selectAll("rdbCancel");
});
});
</script>
<script type="text/javascript" language="javascript">
$(document).ready(function () {
//This handles the rows or colums selection
$("#<%=rdbReplaceAll.ClientID%>").click(function() {
selectAll("rdbReplace");
});
});
</script>
<script type="text/javascript" language="javascript">
$(document).ready(function () {
//This handles the rows or colums selection
$("#<%=rdbRenameAll.ClientID%>").click(function() {
selectAll("rdbRename");
});
});

Use the value as a selector like so
function selectAll(option) {
var radio = $("input[value=" + option + "]");
$(radio).prop("checked", "checked");
}
$('input[type="button"]').on('click', function(){
var value = $(this).data('attr');
selectAll(value);
});

PS : i have more than 1 checkboxes and textboxes depending on my database file
thanks before and forgive me for my bad english skill :)
You should use jQuery to check whether the checkbox is checked.
Say you have a checkbox with id='idTag', and we would like to check whether the checkbox is checked or not.
$('#idTag').is(":checked")
This returns true should the Checkbox be checked; from that moment on you could use jQuery to either show the were it hidden, or append it to the div.
say the text input box has id 'textId'.
Method one:
if($('#idTag').is(":checked"))
$("#textId").css("display", "block"); //if you just like to show the block.
if($('#idTag').is(":checked"))
$("#textId").fadeIn("slow"); //Gives it a nice effect as well.
Method two:
<div id='DIV'>
<input type='checkbox' id='idTag' value='checkbox'/>
</div>
<script>
if($('#idTag').is(":checked"))
$("#DIV").append("<input type='text' placeholder='textbox' />");
</script>
You could simplify your function
DEMO http://jsfiddle.net/x8dSP/2853/
<script>
function enable_txtbox(id){
if(document.getElementById(id).disabled == true){
document.getElementById(id).disabled = false;
} else {
document.getElementById(id).disabled = true;
}
return true;
}
</script>
I hope this solves your problem.
Script...
function enable_txtbox(id){
if(document.getElementById(id).disabled){
document.getElementById(id).disabled=false;
var x = document.getElementById(id).disabled;
document.getElementById("demo").innerHTML=x;
} else {
document.getElementById(id).disabled=true;
var x = document.getElementById(id).disabled;
document.getElementById("demo").innerHTML=x;
}
}
