JQuery, Find results in table column - javascript

Im trying to find the results in a table column if its set in my function below, most of this was setup by someone else, ive just added some extras into it, my final one is searching 1 column only by name set in the thead but alas in its current edition nothing happens at all :|
thanks for any help
USAGE
<a href='javascript:searchTable("Bob", "table",1,"Name");'>Test</a>
TABLE
<table id="table" class="table">
<thead>
<tr>
<th id="blank"> </th>
<th id="Name">Name</th>
<th id="Dept">Department</th>
<th id="JobTitle">Job Title</th>
</tr>
</thead>
<tbody>
<tr>
<td> </td>
<td>Bob</td>
<td>IT</td>
<td>IT Support</td>
</tr>
<tr>
<td> </td>
<td>Fred</td>
<td>Finance</td>
<td>Finance Man</td>
</tr>
</tbody>
</table
FUNCTION
function searchTable(inputVal, tablename,starts, column) {
var table = $(tablename);
table.find('tr:not(.header)').each(function (index, row) {
if (column != '') {
//Columnname
var Cells = $(row).find('td').eq(column);
} else {
//AllCells
var Cells = $(row).find('td');
}
if (Cells.length > 0) {
var found = false;
Cells.each(function (index, td) {
if (starts == 1) {
var regExp = new RegExp((starts ? '^' : '') + inputVal, 'i');
} else {
var regExp = new RegExp(inputVal, 'i');
}
if (regExp.test($(td).text())) {
found = true;
return false;
}
});
if (found == true) $(row).show().removeClass('exclude'); else
$(row).hide().addClass('exclude');
}
});
}

As you're passing the column as a string, you need get the corresponding elements index:
var Cells = $(row).find('td:eq(' + $('#' + column).index() + ')');
The above presumes that you're matching based on the id, if you're matching based on the text within the <th> you could use the :contains selector:
$(row).find('td:eq(' + $(table.prop('id') + ' th:contains(' + column + ')').index() + ')');
If you can control and modify the function calls, the best thing to do would be to just pass the elements index directly to the function:
javascript:searchTable("Bob", "table", 1, 1); <-- Would be the "Name" column
That way, you won't have to do any of the above.
By the way, your table selector is incorrect based on your comment, not sure if that's just a typo on your part?
var table = $(tablename);
Should be:
var table = $('#' + tablename);

I am not sure what you are trying to control but you can use this to loop through rows and get the values of cells.
$("#table>tbody>tr").each(function(){
var name= $(this).children("td").eq(1).html();//Name
var department= $(this).children("td").eq(2).html();//Department
var jobTitle= $(this).children("td").eq(2).html();//Job Title
alert(name);
});

Edit:
You can try this searchTable function.
function searchTable(name,tableName,row,column){
var $Tds= $("#"+tableName+">tbody>tr").eq(row-1).children("td");
if(column=="Name"){
$Tds.eq(1).html(name);
}
else if(column=="Dept"){
$Tds.eq(2).html(name);
}
else if(column=="JobTitle"){
$Tds.eq(3).html(name);
}
}

Usage: This will update the name column of 2nd row of tbody to 'Bob'
searchTable("Bob", "table",2,"Name")

How to include a clickable link or button for each record? HTML + Array + Tables

I have learnt a sample code from youtube on putting an array in HTML table dynamically that is sortable. Below is the code.
How do I made each record in display HTML table clickable and call a myFunction()? The myFunction() will then get the value of the Name in the respective row and execute another query.
HTML Part ->
<table class="table table-striped">
<tr class="bg-info">
<th data-column="name" data-order="desc">Name &#9650</th>
<th data-column="age" data-order="desc">Age &#9650</th>
<th data-column="birthdate" data-order="desc">Birthday &#9650</th>
</tr>
<tbody id="myTable">
</tbody>
the javascript part
var myArray = [
{'name':'Michael', 'age':'30', 'birthdate':'11/10/1989'},
{'name':'Mila', 'age':'32', 'birthdate':'10/1/1989'},
{'name':'Paul', 'age':'29', 'birthdate':'10/14/1990'},
{'name':'Dennis', 'age':'25', 'birthdate':'11/29/1993'},
{'name':'Tim', 'age':'27', 'birthdate':'3/12/1991'},
{'name':'Erik', 'age':'24', 'birthdate':'10/31/1995'},
]
$('th').on('click', function(){
var column = $(this).data('column')
var order = $(this).data('order')
var text = $(this).html()
text = text.substring(0, text.length - 1)
if(order == 'desc'){
$(this).data('order', "asc")
myArray = myArray.sort((a,b) => a[column] > b[column] ? 1 : -1)
text += '&#9660'
}else{
$(this).data('order', "desc")
myArray = myArray.sort((a,b) => a[column] < b[column] ? 1 : -1)
text += '&#9650'
}
$(this).html(text)
buildTable(myArray)
})
buildTable(myArray)
function buildTable(data){
var table = document.getElementById('myTable')
table.innerHTML = ''
for (var i = 0; i < data.length; i++){
var row = `<tr>
<td>${data[i].name}</td>
<td>${data[i].age}</td>
<td>${data[i].birthdate}</td>
</tr>`
table.innerHTML += row
}
}
My Function Call Js part
function myFunction() { " wanna get the value of the row if link is click" }
You need to add the following after you call the buildTable(myArray) so the <tr> tags can render before you assign them a click event.
$('tr').click(function(){
var name = $(this).children('td').first().html();
yourFunction(name);
});
function yourFunction(name){
//do things with name here
}
Also, this assumes that the first td will always contain the name. A better implementation would be to refactor the buildTable function and give classes to your td
$(document).on("click", "tbody tr", function(){
//if you want name field
$(this).find("td:nth-child(1)").text();
//if you want age field
$(this).find("td:nth-child(2)").text();
});
i done the myFunction in Jquery, use this code inside your script tag

td background colouring applied to complete column rather to a single cell

I've below html.
<table border="1" class="myTable">
<tr>
<th class="cname">Component</th>
<th class="pname">Properties</th>
<th class="sname">lqwasb02</th>
</tr>
<tr>
<td class="cname">EMWBISConfig</td>
<td class="pname">reEvaluationTimer</td>
<td class="pvalue">every 1 hour without catch up</td>
</tr>
<tr>
<td class="cname">CalculateCategoryMediaInfoService</td>
<td class="pname">scheduled</td>
<td class="pvalue">yes</td>
</tr>
<tr>
<td class="cname">EMWBISScheduler</td>
<td class="pname">scheduled</td>
<td class="pvalue">no</td>
</tr>
<tr>
<td class="cname">CatalogTools</td>
<td class="pname">loggingDebug</td>
<td class="pvalue">false</td>
</tr>
</table>
Below is the jquery I've written.
$(document).ready(function(){
var list = ['every 1 hour without catch up','yes','yes','false'];
$.each(list,function(index,value){
//alert(index+' : '+value);
});
var idx;var list2 = new Array();
// Find index of cell with 'lqwasb02'
$('.myTable th').each(function(index) {
if ($(this).text() === 'lqwasb02') idx = index;
});
// Loop through each cell with the same index
$('.myTable tr').each(function() {
if($(this).find('td:eq('+idx+')').text() !=""){
list2.push($(this).find('td:eq('+idx+')').text());
}
}); var idx2 = [];
for(var x=0;x<list2.length;x++){
if(list[x]===list2[x]){
//console.log(list[x]);
}else{
console.log('mismatched : '+list[x]);
$('.myTable tr').each(function() {
$(this).find('td:eq('+x+')').css("background-color", "red");
});
idx2.push(x);
}
}
});
I'm trying to compare values in list with values in lqwasb02 column and if it finds the difference, it should highlight the background of td cell in red colour.
Current issue with jquery code, it is highlighting the complete column.
Can someone please help me where I'm getting wrong? If possible, please pass on the recommended solutions.
Many Thanks in advance.
The problem is that in your .find you are returning multiple elements that it's selector matches. So as opposed to storing the text value for your td elements in the second array, just store the actual td element, compare it's text, and then you can assign the background color directly to the element as opposed to finding it again via it's index:
$(document).ready(function(){
var list = ['every 1 hour without catch up','yes','yes','false'];
$.each(list,function(index,value){
//alert(index+' : '+value);
});
var idx;var list2 = new Array();
// Find index of cell with 'lqwasb02'
$('.myTable th').each(function(index) {
if ($(this).text() === 'lqwasb02') idx = index;
});
// Loop through each cell with the same index
$('.myTable tr').each(function() {
if($(this).find('td:eq('+idx+')').text() !=""){
list2.push($(this).find('td:eq('+idx+')')); // <-- Store the object here, not it's text value.
}
});
var idx2 = [];
for(var x=0; x < list2.length; x++){
if(list[x]===list2[x].text()) { // <-- compare list[x] to the text value of list2[x]
//console.log(list[x]);
} else {
list2[x].css("background-color", "red"); // <-- no find or selector needed, just apply it to the object you stored earlier.
};
idx2.push(x);
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table border="1" class="myTable">
<tr>
<th class="cname">Component</th>
<th class="pname">Properties</th>
<th class="sname">lqwasb02</th>
</tr>
<tr>
<td class="cname">EMWBISConfig</td>
<td class="pname">reEvaluationTimer</td>
<td class="pvalue">every 1 hour without catch up</td>

<td class="cname">CalculateCategoryMediaInfoService</td>
<td class="pname">scheduled</td>

<td class="pvalue">false</td>
</tr>
</table>
$('.myTable tr').each(function() {
$(this).find('td:eq('+x+')').css("background-color", "red");
});
this piece of code assign a background colour to each cell of index 'x' for each rows (each cells of index x of each table rows represent a column).
You have to select only the rows which contains the cells you want to colour.
Here is how i would have approached solving this issue:
$(document).ready(function(){
var list = ['every 1 hour without catch up','yes','yes','false'];
var colIndex = findColIndex('lqwasb02');
// Loop over table rows
$('tr').each(function(){
// Look up cell with specific index
var $cell = $(this).find('td').eq(colIndex);
// Check if the text of the cell is not present in the list and do smth
if ($.inArray($cell.text(), list) === -1) {
$cell.css('background', 'red')
}
});
});
// helper function to find the index of column by text in the header
function findColIndex (headerText) {
var $col = $('.myTable th:contains(' + headerText + ')');
return $('.myTable th').index($col);
}

Looping object inside a table cell and create a unordered list

I have this table that has a column in which the cell may or may not contain a value, but when it does, it is in a JSON format; otherwise it will be empty (null).
<table>
<tbody>
<tr>
<td>Barley</td>
<td>AK, AZ</td>
<td class="fpdCell">[{"date":"06/01/2016","error":"Double/Triple cropping","id":2},{"date":"06/07/2016","error":"Lack of Planting Dates Established","id":2}]</td>
<td>null</td>
</tr>
<tr>
<td>Barley</td>
<td>AK, AZ, AR</td>
<td class="fpdCell">[{"date":"06/04/2016","error":"No Error Found","id":3},{"date":"06/27/2016","error":"Lack of Planting Dates Established","id":3},{"date":"06/28/2016","error":"Weather Patterns","id":3}]</td>
<td>null</td>
</tr>
<tr>
<td>Burley Tobacco</td>
<td>null</td>
<td class="fpdCell">null</td>
<td>null</td>
</tr>
<tr>
<td>Fire Cured Tobbacco</td>
<td>null</td>
<td class="fpdCell">null</td>
<td>null</td>
</tr>
<tr>
<td>Flue Cured Tobacco</td>
<td>null</td>
<td class="fpdCell">null</td>
<td>null</td>
</tr>
<tr>
<td>Oats</td>
<td>null</td>
<td class="fpdCell">null</td>
<td>null</td>
</tr>
What I need to do is to loop through each of the cells with the fpdCell class, loop the object inside of each of those cell, create a list and add them as list element.
This is as far as I was able to get. I really don't know how to move forward from here.
var theCells = $('.fpdCell');
$.each(theCells, function(index, value) {
var cellValues = $.parseJSON(value.textContent);
if (cellValues != 'null') {
console.log(cellValues);
value.textContent = '';
$(value).append('<ul class="list-group ul'+index+'"></ul>')
//then add <li class="list-group-item">Test</li>
//Not working------------------
/*
for (var u = 0; u < cellValues. length; u++) {
$('ul' + index).append('<li class="list-group-item">'+cellValues[u].date+'</li>');
console.log(cellValues[u].date);
}
*/
}
});
Thanks in advance.
To achieve this you just need two loops, one to go through the .fpdCell elements, the other to go through the parsed JSON and build the HTML of the ul. Try this:
$('.fpdCell').each(function() {
var $el = $(this), html = '';
$.each(JSON.parse($el.text()), function(i, obj) {
html += '<li class="list-group-item">' + obj.date + '</li>';
})
$el.append('<ul>' + html + '</ul>');
});
Working example
var theCells = $('.fpdCell');
$.each(theCells, function() {
var cellValues = $.parseJSON($(this).text());
if (cellValues != 'null') {
console.log(cellValues);
$(this).html("");
var list = '<ul class="list-group ul'+index+'">';
for (var u = 0; u < cellValues.length; u++) {
list+='<li class="list-group-item">'+cellValues[u].date+'</li>';
console.log(cellValues[u].date);
}
if(cellValues.length>0)
list+="</ul>";
$(this).append(list);
}
The objects in the fpdcell columns are array objects which you may have missed in your logic.
One more thing, may be a typo, but, you missed the . in the commented code to append list items to the ul :)
Here is a solution which loops through the array and then loops through the individual elements in each array element to create a linear list.
var theCells = $('.fpdCell');
$.each(theCells, function(index, value) {
var cellValues = JSON.parse(value.textContent);
if (cellValues != 'null') {
$(value).html('<ul class="list-group ul'+index+'"></ul>');
$.each(cellValues, function(cellValueIndex, cellValue){
for (var prop in cellValue) {
$('.ul'+index).append('<li class="list-group-item">'+ cellValue[prop] +'</li>');
}
});
} else {
$(value).html('');
}
});
This may not be the exact solution to what you are looking for but, should help you along the line you would want to go. Happy coding.
Here is a fiddle with the solution JSFiddle

Filtering table rows upon Search

I am trying to filter the rows of a table to display the results of entered text in the search bar. The code below does the job but for some reason filters the column headings as well.
$('#search').keyup(function () {
var data = this.value.split(" ");
var rows = $(".Info").find("tr").hide();
if(this.value ==""){
rows.show();
return;
}
rows.hide();
rows.filter(function(i,v){
var t = $(this);
for (var d = 0; d < data.length; d++) {
if (t.is(":Contains('" + data[d] + "')")) {
return true;
}
}
return false;
}).show();
});
HTML
<input type = "search" name = "search" id = "search">
<table style ="width:95%" class = "Info">
<tr>
<th>Select </th>
<th>Name</th>
<th>Number</th>
<th>Date</th>
</tr>
</table>
The user adds rows which is why i haven't written any HTML for it.
Any help would be appreciated. Thanks in advance
http://jsfiddle.net/szjhngwm/
It looks like you need to filter using tbody
<table style ="width:95%" class = "Info">
<thead>
<tr>
<th>Select </th>
<th>Name</th>
<th>Number</th>
<th>Date</th>
</tr>
<thead>
<tbody>
</tbody>
</table>
var rows = $(".Info tbody tr").hide();
Another way to do this would be to use jQuery's :gt() selector.
The only thing that would change is this line:
var rows = $(".Info").find("tr:gt(0)").hide();
Notice the addition of :gt(0) to your tr.

get values from table as key value pairs with jquery

I have a table:
<table class="datatable" id="hosprates">
<caption> hospitalization rates test</caption> <thead>
<tr>
<th scope="col">Funding Source</th> <th scope="col">Alameda County</th> <th scope="col">California</th>
</tr>
</thead>
<tbody>
<tr>
<th scope="row">Medi-Cal</th>
<td>34.3</td>
<td>32.3</td>
</tr>
<tr>
<th scope="row">Private</th>
<td>32.2</td>
<td>34.2</td>
</tr>
<tr>
<th scope="row">Other</th>
<td>22.7</td>
<td>21.7</td>
</tr>
</tbody>
</table>
i want to retrieve column 1 and column 2 values per row as pairs that end up looking like this [funding,number],[funding,number]
i did this so far, but when i alert it, it only shows [object, object]...
var myfunding = $('#hosprates tbody tr').each(function(){
var funding = new Object();
funding.name = $('#hosprates tbody tr td:nth-child(1)').map(function() {
return $(this).text().match(/\S+/)[0];
}).get();
funding.value= $('#hosprates tbody tr td:nth-child(2)').map(function() {
return $(this).text().match(/\S+/)[0];
}).get();
});
alert (myfunding);
var result = $('#hosprates tbody').children().map(function () {
var children = $(this).children();
return {
name: children.eq(0).text(),
value: children.eq(1).text()
};
}).get();
This will build an array in the form:
[
{ name : "...", value: "..." },
{ name : "...", value: "..." },
{ name : "...", value: "..." }
]
etc
To get the name of the first row, use:
alert(result[0].name);
For the value:
alert(result[0].value);
Edit: if you want the result EXACTLY as you specify:
var result = $('#hosprates tbody').children().map(function () {
var children = $(this).children();
return "[" + children.eq(0).text() + "," + children.eq(1).text() + "]"
}).get().join(",");
Try this then (demo):
var funding = $('#hosprates tbody tr').map(function(){
return [[ $(this).find('th').eq(0).text() , // find first and only <th>
$(this).find('td').eq(0).text() ]]; // find first <td> in the row
}).get();
alert(funding); // Output: Medi-Cal,32.3,Private,34.2,Other,21.7
The alert display only shows the data inside the array, it is actually formatted like this:
[["Medi-Cal", "32.3"], ["Private", "34.2"], ["Other", "21.7"]]
So you could get the Medi-Cal data like this:
alert(funding[0][0] + ' -> ' + funding[0][1]); // output: Medi-Cal -> 34.3
