Target specific row in SQLite (Cordova) - javascript

Please help. I'm looping through rows and display the items in a list. When I click a row, I need to get the row name. I think I need to get the rowid but I'm not sure how. All the below code is getting is the last row name.
db.transaction(function(tx) {
tx.executeSql('CREATE TABLE IF NOT EXISTS client (name TEXT)');
tx.executeSql('SELECT * FROM client', [], function (tx, results) {
for(var x = 0; x < results.rows.length; x++) {
var $single = results.rows.item(x);
var $singleName = $single.name;
var $wrapper = $('<div class="client-row" />').appendTo('.client-list');
$wrapper.append ('<div class="client-name">' + $singleName + '</div>');
$(document).on("click", ".client-row", function(){
$(".indiv-client").show();
$(".current-client").text($singleName);
});
}
});
});

Your on function is defining the behaviour of every element with class="client-row" Therefore when you run it in the loop like this it will set every client row element to be $singleName
simply create the div as
'<div class="item" data-name="' + $singleName +'" />'
and then use .attr('data-name'); to retrieve it (oh and set the .on behaviour outside of the loop)

SetVariable(var count, var count)

As the code below shows, I am appending a table with some table rows containing table data. The table data is getting appended with excel formula inside. How can I change the count variable inside td.class after it was appended in table upon click event or something similar.
I Want to update td.excel count attribute with onclick event
.append("<td class="
excel " x:num x:fmla=\"=SUM(H" + count + " *I" + count + ")
$("#example").on("click", "button", function() {
$(this).closest("tr").remove();
count--;
var i = 10;
for (i = 10; i < count; i++) {
let div1 = document.getElementsByClassName("excel");
var attribute = div1.SetAttribute(count, count);
}
}
Your problem is not clear. But what I've got from your question is that you want to dynamically append to . But you end up with excel formula getting inside it.
So, according to me when you want to insert something dynamically then you should use `` these quotes instead of '' and "". eg :-
var i = 1;
.append(`<td class="hello${i}"></td>`)

JQuery Datatable rows not deleting despite on calling clear function

Im trying to remove all the rows in jquery data tables when new data arrives in order to fill with new rows.
But the problem is despite calling clear function it simply add the result rows to previous rows.
How to clear the rows in jquery data tables . Following is the code
var table = $("#editable");
var tp = table.DataTable({
"paging": true,
"createdRow": function (row, data, index) {
$compile(row)($scope);
}
});
//more code here ajax call only from angular post
if (result != null) {
$scope.reviews = result;
$window.toastr["success"]("Loaded Successfully !", "Recent Reviews");
tp.clear().draw();
for (var i = 0; i < $scope.reviews.length; i++) {
var id = $scope.reviews[i].ID;
var checked = $scope.reviews[i].Enabled == "1" ? true : false;
tp.row.add([
$scope.reviews[i].ID,
$scope.reviews[i].AddedOn,
$scope.reviews[i].Company.Name,
$scope.reviews[i].Rate,
$scope.reviews[i].User.Name,
$scope.reviews[i].Description,
"<div class='switch'><div class='onoffswitch'><input ng-model='$scope.reviews[" + i + "].Enabled' ng-click='ChangeReviewPublishStatus(" + $scope.reviews[i].ID + ")' ng-checked='" + checked + "' class='onoffswitch-checkbox' id= 'stat" + id + "' type= 'checkbox'><label class='onoffswitch-label' for='stat" + id + "'><span class='onoffswitch-inner'></span><span class='onoffswitch-switch'></span></label></div></div>"
]).draw();
}
}
I would place that piece of code inside a $timeout. Both dataTables and angular wants to manipulate the DOM - angular wins the battle and by that dataTables never get a chance to finish its business. A $timeout will force the dataTables clear() and data population into the next digest, and ensure it is actually executed.
$timeout(function() {
tp.clear().draw();
for (var i = 0; i < $scope.reviews.length; i++) {
var id = $scope.reviews[i].ID;
var checked = $scope.reviews[i].Enabled == "1" ? true : false;
tp.row.add([
$scope.reviews[i].ID,
$scope.reviews[i].AddedOn,
//etc
]).draw();
}
});
Well, that is at least my theory - cannot replicate your scenario in full - let me know if it makes any difference.

Append contents of each div to textarea

I have a list of divs created server-side, each with a price, quantity (entered by the user) and name. I've managed to use jQuery to calculate the total of each and add those up.
What I'd like to do now is to list the name, quantity and total of each item that has a value in my textarea, on a per-row basis.
So far I've got the following (the append part of which doesn't currently work):
$(document).ready(function () {
$(".product-row input").change(multInputs);
function multInputs() {
var mult = 0;
// for each row:
$("div.product-row").each(function () {
// get the values from this row:
var $price = $('.price', this).html();
var $quantity = $('.quantity', this).val();
var $total = ($price * 1) * ($quantity * 1);
// set total for the row
$('.multTotal',this).text($total);
mult += $total;
$('#textarea',this).append($name).append($total);
});
$("#total").html(mult);
}
});
If I can get this worked out, I'm pretty sure I can work out how to add the grand total and clear the textarea each time something is changed (I'm not looking for someone to do all the work).
Any feedback as to why my textarea isn't populating would be very much appreciated.
Edit: The solution, really well explained below by braks has resulted in the following (working!) code:
$(document).ready(function () {
$(".product-row input").change(multInputs);
function multInputs() {
var mult = 0;
// for each row:
$("div.product-row").each(function () {
// get the values from this row:
var price = $('.price', this).html();
var quantity = $('.quantity', this).val();
var name = $('.name', this).html();
var total = (price * 1) * (quantity * 1);
// set total for the row
$('.multTotal',this).text(total);
mult += total;
$('#textarea').val($('#textarea').val() + ' ' + name + ' ' + total);
});
$("#total").html(mult);
}
});
$(textarea).append(txt) doesn't work like you think. When a page is loaded the text nodes inside the textarea are set the value of that form field. After that, the text nodes and the value can be disconnected. As you type in the field, the value changes, but the text nodes inside it on the DOM do not. Then you change the text nodes with the append() and the browser erases the value because it knows the text nodes inside the tag have changed.
So you want to set the value, you don't want to append. Use jQuery's val() method for this.
You have to use something like $('#textarea').val($('#textarea').val() + ' ' + $name + ' ' + $total);
Except I'm not sure why you put $ in your variables, mix up with PHP ?

Issue in adding one table row to a table when similar multiple tables are present on a webpage?

I've a form in which containing one <div> tag and the HTML within it. This is what I've when page loads. Then through AJAX I'm appending the same block(i.e. ) to the existing one. In every <div> tag there is one <table> and in that <table> I've a button with class products. After clicking on it I'm calculating the no. of rows present in that table only and assigning the id to the newly added row. But the issue I'm facing is when I add multiple such tables using AJAX and click on add button of any table it's calculating the total no. of rows present in all tables and adding that much no. of rows to the table in which I clicked add button. This shouldn't have to happen. It has to add only one row. I've created a jsfiddle for your reference. In fiddle I've put in static HTMl so it's working fine over there but on my local machine when I add multiple tables using AJAX I'm getting wrong no. of rows added.For example if I added three tables and click on add button of first table then it's adding four rows to that table. Why it's counting the total no. of rows present in all the tables present on a page?Is there any need to improve my script? My script is as follows:
$(document).ready(function() {
$('.products').click(function () {
var table_id = $(this).closest('table').attr('id');
var no = table_id.match(/\d+/)[0];
//var first_row = $(this).closest('table').find('tbody tr:first').attr('id');
var first_row = $('#'+table_id).find('tbody tr:first').attr('id');
var new_row = $('#'+first_row).clone();
var tbody = $('tbody', '#'+table_id);
var n = $('tr', tbody).length + 1;
new_row.attr('id', 'reb' + no +'_'+ n);
$(':input', new_row).not('.prod_list').remove();
$('select', new_row).attr('name','product_id_'+no+'['+n+']');
$('select', new_row).attr('id','product_id_'+no+'_'+n);
$('<button style="color:#C00; opacity: 2;" type="button" class="close delete" data-dismiss="alert" aria-hidden="true">×</button>').appendTo( $(new_row.find('td:first')) );
tbody.append(new_row);
$('.delete').on('click', deleteRow);
});
});
Following is jsFiddle link: http://jsfiddle.net/vrNAL/2/
I think what you mean to query is this:
var tbody = $('#' + table_id + ' tbody');
Instead of:
var tbody = $('tbody', '#' + table_id);
From the jQuery documentation, I don't think selectors work this way.
You are doing some strange things with the IDs here. why are you getting the IDs and selecting the sleemts with that, instead of using the selected elements directly?
Example:
var table_id = $(this).closest('table').attr('id');
var table = $("#" + table_id);
Is the same as just
var table = $(this).closest('table');
and
var first_row = $('#'+table_id).find('tbody tr:first').attr('id');
var new_row = $('#'+first_row).clone();
is the same as:
var new_row = table.find('tbody tr:first').clone();

Append a header to dynamically-loaded tables using JQuery

I've been having a hard time trying to append new headers to tables I build dynamically using data grabbed from an AJAX call.
I've already asked here a question about my problem, but it seems that there's no logical answer to it.
So my problem is that I can't actually get the table I want to append my new info to, what I tired was this:
console.log(id); //This prints the right id!
//THIS is not working...
$('#'+id+' tr:first').append("<td>Well "+(wellCounter)+"</td>");
//...
//$('#'+401+' tr:first').append("<td>Well "+(wellCounter)+"</td>");--this will work
table+="<td>M "+fourthLevel.male+"</td>";
table+="<td>H "+fourthLevel.herm+"</td>";
But it didn't work, so I was wondering if you can help me with another way to get the same functionality without using the id to get the table. Maybe the closest function will work but I don't have experience with that, and I tried it but failed.
Here the full code:
$.each(data, function(index, firstLevel) {
$.each(firstLevel, function(index2, secondLevel) {
var id = firstLevel['id'];
var author = firstLevel['author'];
var date = firstLevel['date'];
var experimental_conditions = firstLevel['experimental_conditions'];
if(index2 == 'items'){
var table = '<div class=tableWrapper><table id=\"'+id+'\" class=\"experimentTable\">';
table += '<input id=\"basketButton\" type=\"submit\" value=\"Add to basket\" class=\"basketButton\" experimentBatch=\"'+id+'\"> <div class="superHeader"><span class=\"superHeader\">Date: '+date+', By '+author+'</span><br /><span class=\"subHeader\">Experimental conditions: '+experimental_conditions+'</span>'
table += '<tr><td></td><td COLSPAN=2>Totals</td></tr>';
table += '<tr id="header"><td width="20%">Genotype</td><td width="10%"><img src="images/herma.png"></td><td width="10%"><img src="images/male.png"></td>';
//for each table
$.each(secondLevel, function(index3, thirdLevel) {
var nWells = 0;
table += "<tr><td>"+thirdLevel['mutant_name_c']+"</td><td>"+thirdLevel['herm_total']+"</td><td>"+thirdLevel['male_total']+"</td>";
currentRow = 3;
wellCounter = 0;
//for each row
$.each(thirdLevel, function(index4, fourthLevel) {
wellCounter++;
if (fourthLevel.date_r != undefined){
console.log(id);
//THIS is not working...
$('#'+id+' tr:first').append("<td>Well "+(wellCounter)+"</td>");
//...
table+="<td>M "+fourthLevel.male+"</td>";
table+="<td>H "+fourthLevel.herm+"</td>";
}
});
});
table +='</table></div>'
$('#searchResults').append(table);
}
});
});
NOTE: Male and herm are worm genders, not options!
I didn't go through your code, but when I'm working with dynamic table in jquery i try with Jquery "OBJECT". something like
var $tbl = $('<table />'), $tr=$('<tr />'), $td=$('<td />');
then you can add attr, append etc, and is much easier to read, and manipulate.
$tbl.attr('id',id).append($tr.append($td);
etc.
