I am developing an MVC app in which I have created two tables in view dynamically. In each table first column contains ID and last column contains save button. On click of save button I'm passing this ID to my function. Now I want to check the button was clicked from which table so that I can perform operations. I have tried many solutions but did not work. Can anybody help?
function SaveDocument(_param) {
//alert(_param + "Add");
return;
var tableRow = $("td").filter(function () {
return $(this).text() == String(_param);
}).parent('tr');
tableRow.parent().attr('uid');
}
and I have also tried links like this but none of these work.
Edit : -
I have created fiddle for this here
You mentioned that you're creating tables dynamically, so I'm assuming your click event won't fire unless you delegate it.
Try adding a class say .save to the buttons and run the below code.
$(document).on('click', '.save', function(){
console.log($(this).closest('table'));
});

I have a table with rows generated through jquery, and I want the temperature column to auto update and get its latest value through an http request.
So in order to select those cells, since they're dynamically generated, I used .on() and it works fine with events like click and mouseenter.
But since there are multiple rows, I thought I would use something like setInterval, but it's not working and I don't know why, event without the set interval or a custom event.
After searching similar issues, I suspect that trigger() doesn't work well with elements added with jQuery. So any ideas on how I can get around this so that the cell value is updated?
Here's the relevant bit of code:
<p id='showData'>
<table id="display-table" class="display-table"></table>
</p>
$(document).ready(function(){
DisplayList();
$("table").on('mouseenter', ".temp", function(){
var cellTemp = this;
console.log("this is :" +here.id);
console.log(ceci);
UpdateTemp(cellTemp.id, cellTemp.id, cellTemp.className).then(function(value){
cellTemp.innerHTML=(value);
});
});
$(document).on('test', '.name', function () { alert("hello"); });
$("table").trigger('mouseenter');
});
Suppose there is Table with variable number of rows of fixed number of columns, and suppose each row has a button too, now I want to select for example a column's value(let's say this selected column is textarea, so I select it's content) when that row's button is clicked.
For example in above image I want that if submit is pressed than all data of 'textarea' of corresponding row should be stored in a variable.
You can use the jQuery closest() function to find an element near the clicked button. Add click handlers to the buttons and then traverse up to find the textarea.
$('.button').on("click",function(){
var thisRowsTA = $(this).closest("textarea");
console.log($(thisRowsTA).val());
});
A simply way is to:
Put an ID pattern to your textareas, like: txt_area_1, txt_area_2, txt_area_3.
Then, on the Click Event of your buttons, make them catch the corresponding textarea in their row. Use the ID patterns to do this.
Post your code for further help.
You will need to ad an event handler for each button. Inside of that you can write something like this.
function eventHandler(e){
var row = this; // start at the button
while(row.nodeName != 'TR' && row.parent){
// go up till we find the row
row = row.parent;
}
var textArea = row.querySelector('textarea');
var value = textArea.value;
// do something with supplied feedback.
}
In order to attach the handlers, you would do something like this.
function attachTableEvents(){
var table = document.querySelector('table'); // or more specific selector if needed
var buttons = table.querySelectorAll('button');
for (var i = buttons.length; i--;){
buttons[i].addEventListener(eventHandler);
}
}
Counting on the DOM structure is really BAD.
I would put an attribute in my controls that holds the line number. Then when clicking an element you can easily query the DOM by element type and the property value to get any elements in this line.
Later if you change to DIVs or change structure your will still run correctly
I'm trying to create form for printing with dynamically generated inputs.
Contents of the fields is shown later in PreviewDiv.
It works fine as long as I specify where they should be, for example:
$('#Prw_CapacityA_1').text($('#CapacityA_1').val());
$('#Prw_CapacityB_1').text($('#CapacityB_1').val());
$('#Prw_CapacityC_1').text($('#CapacityC_1').val());
But if the user creates 100 fields this would be a lot of code to write.
There must be other methods to fix this dynamically, for example:
$('#Prw_CapacityA_'+ counter).text($('#CapacityA_'+ counter).val());
Here's the js fiddle
You could try using attribute starts with selector to select the elements starting with the specific id's and then loop through them using the each() function.
There is no need to have html within your preview table. You can generate it when the user clicks on preview. Modified fiddle
$('#PreviewButton').click(function(){
var capB = $('td input[id^=CapacityB_]');
var capC = $('td input[id^=CapacityC_]');
var table = $("#AddFieldsToPreviewDiv");
table.empty(); //build table everytime user previews so that previously appended values are removed
table.append('<tr><td>ID</td><td>Text 1</td><td>Text 2</td><td>Text 3</td></tr>');
$('td input[id^=CapacityA_]').each(function(i){
table.append('<tr><td>#'+(i + 1)
+'</td><td>'+$(this).val()
+'</td><td>'+$(capB[i]).val()
+'</td><td>'+$(capC[i]).val()
+'</td></tr>');
});
// Show PreviewDiv and hide FormDiv if PreviewButton clicked
$('#PreviewDiv').show();
$('#FormDiv').hide();
});
You could try giving them a unique class (Normally I'd suggest ID but you're using one) say a class of "getinfo"
You could then try the .each() function
https://api.jquery.com/each/
$( ".getinfo" ).each(function( index ) {
var text = $(this).val();
alert(text);
});
This will make an alert box for every element it finds with the class 'getinfo' and then retrieve the value and display it, I hope this gives you a better idea.
If the amount of inputs can change from one page load to the next then you need to use a loop, rather than pulling all the values by 'hand', More code will help better understand what you're trying to achieve and from what.
There is a one table where user can select multiple rows, and below to the table there is two buttons moveup and move down. when user will click on movebutton, rows should go move up, similar to movedown.
Below is my Jquery code
$(".moveUp").live("click", function(){
var row = $(".selectRow")
$(row).each(function() {
row.insertBefore(row.prev());
});
});
But it is behaving very wrong. Please help me. I am new in jquery.
Thanks!
You need to try like this
$(".moveUp").on("click", function() {
var row = $(".selectRow");
row.each(function() {
var $this=$(this);
$this.insertBefore($this.prev());
});
});
there is no need to wrap row using $( ) again
An alternate approach is to manipulate an array of pure data (store row and selected state), then trigger a 'render' function on the data after it is changed. IOW, redraw the entire table on each operation. Typically this is fast, and an advantage is you can separate the logic/data from the visual interface (like MVC style).
I'm trying to create a table of inputs that automatically adds a new row when you enter text in one of the inputs on the bottom line. For the most part, it works fine. However, I'm having some trouble with jQuery UI checkbox buttons.
The checkbox buttons are supposed to change their icon when clicked. This works fine for the original buttons, but the cloned button that appears when you add a new row doesn't work properly.
You can see it in jsfiddle here. To replicate the issue, put some text in the third input down. You'll see that a fourth row appears. If you press the fourth checkbox, you'll see the third checkbox is the one whose icon changes. The wrong button also gets ui-state-focus but doesn't actually get focus, which really baffles me, though the correct button does get ui-state-active and seems, as far as I can tell, to evaluate as having been checked properly.
To be clear, the two checkboxes do not have the same ID, and their labels are for the right checkbox - the createNewRow() function takes care of that. If you comment out the line that turns the checkboxes into jQuery UI checkboxes, you'll see everything works fine. If you console.log the value of $(this).attr('id') in the buttonSwitchCheck function, you'll see that it has the right ID there too - if you click the fourth button, it'll tell you that the id of $(this) is "test4", but it's "test3" (the third button) that gets the icon change.
I'm going mad staring at this and I'd appreciate any help people can give. Here's the code:
// Turns on and off an icon as the checkbox changes from checked to unchecked.
function buttonSwitchCheck() {
if ($(this).prop('checked') === true) {
$(this).button("option", "icons", {
primary: "ui-icon-circle-check"
});
} else {
$(this).button("option", "icons", {
primary: "ui-icon-circle-close"
});
}
}
// Add a new row at the bottom once the user starts filling out the bottom blank row.
function createNewRow() {
// Identify the row and clone it, including the bound events.
var row = $(this).closest("tr");
var table = row.closest("table");
var newRow = row.clone(true);
// Set all values (except for buttons) to blank for the new row.
newRow.find('.ssheet').not('.button').val('');
// Find elements that require an ID (mostly elements with labels like checkboxes) and increment the ID.
newRow.find('.ssheetRowId').each(function () {
var idArr = $(this).attr('id').match(/^(.*?)([0-9]*)$/);
var idNum = idArr[2] - 0 + 1;
var newId = idArr[1] + idNum;
$(this).attr('id', newId);
$(this).siblings('label.ssheetGetRowId').attr('for', newId);
});
// Add the row to the table.
newRow.appendTo(table);
// Remove the old row's ability to create a new row.
row.removeClass('ssheetNewRow');
row.find(".ssheet").unbind('change', createNewRow);
}
$(document).ready(function () {
// Activate jQuery UI checkboxes.
$(".checkButton").button().bind('change', buttonSwitchCheck).each(buttonSwitchCheck);
// When text is entered on the bottom row, add a new row.
$(".ssheetNewRow").find(".ssheet").not('.checkButton').bind('change', createNewRow);
});
EDIT: I was able to find a solution, which I'll share with the ages. Thanks to "Funky Dude" below, who inspired me to start thinking along the right track.
The trick is to destroy the jQuery UI button in the original row before the clone, then reinitializing it immediately afterwards for both the original row and the copy. You don't need to unbind and rebind the change event - it's just the jQuery UI buttons which have trouble. In the createNewRow function:
row.find('.checkButton').button('destroy');
var newRow = row.clone(true);
row.find('.checkButton').add(newRow.find('.checkButton')).button().each(buttonSwitchCheck);
Try using the newer method .on, that allows for delegation, which should help with the dynamic changes to your DOM:
$(".checkButton").button().each(buttonSwitchCheck);
$("table").on("change", ".checkButton", buttonSwitchCheck);
I'm not sure, but it might help with not having to worry about binding events to specific elements.
Also, you could use it for the textbox change event:
$("table").on("change", ".ssheetNewRow .ssheet:not(.checkButton)", createNewRow);
Here's your fiddle with my changes: http://jsfiddle.net/Cugb6/3/
It doesn't function any different, but to me, it's a little cleaner. I thought it would've fixed your problem, but obviously hasn't, due to problems with the button widget.
And funny enough, it doesn't seem they "support" cloning: http://bugs.jqueryui.com/ticket/7959
i think you are using deep clone, which also clones the event handler. in your create new row function, try unbinding the change event then rebind on the clone.
