Believe me, I've been looking for examples online for hours. None of them seem to help.
I'm working on making a table. There are some columns with dropdown menu and I've assigned ID to each menu. Inside a loop, I'm trying to assign selected value for each dropdown menu.
var row$ = $('<tr/>');
function updateDataBodyGenerator(myList) {
for (var i = 0 ; i < myList.length ; i++) {
var row$ = $('<tr/>');
var colIndex = 0;
for (var key in myList[i]) {
var cellValue = myList[i][columns[colIndex]];
if (cellValue == null) { cellValue = ""; }
var severityDropDownMenu = "severityDropDownMenu" + i;
colIndex++;
switch (key) {
case "Test Case":
...
break;
case "Test Result":
...
break;
case "Severity":
var severitySting = '<td><select id="' + severityDropDownMenu + '" class="dropDownMenu">' +
'<option value="Red">Red</option>' +
'<option value="Green">Green</option>'+
'<option value="Yellow">Yellow</option>';
row$.append($(severitySting));
//failed
//$("#severityDropDownMenu" + i).val(cellValue);
//failed
//var selectorString = "#" + severityDropDownMenu.toString();
//$(selectorString).val("Green");
//failed
//$("#" + severityDropDownMenu).val(cellValue);
//failed
//var selectorString = '#' + severityDropDownMenu;
//$(selectorString).val(cellValue);
//works
//$('#severityDropDownMenu0').val(cellValue);
...
As you can see in the comments, I've tried several approaches and only 1 worked which was $('#severityDropDownMenu0').val(cellValue); but that will only change 1 dropdown menu.
I appreciate your time and assistance.
Currently you're trying to use the # selector to target the dropdown by ID.
The issue here (as mentioned in the comments) is that this selector will search the DOM for the element, however because you've never added this element to the DOM, it doesn't exist on the page; the selector will return nothing.
What you can do instead is actually turn your severitySting into a jQuery element to set its value. Whenever you do append it, the value will be properly set. Like so:
var $severity = $(severitySting); //This is the <td>
var $dropdown = $severity.find("select") //This is the <select>
$dropdown.val(cellValue); //Set dropdown value
Demo:
var severityDropDownMenu = "mytest";
var cellValue = "Yellow";
var severitySting = '<td><select id="' + severityDropDownMenu + '" class="dropDownMenu">' +
'<option value="Red">Red</option>' +
'<option value="Green">Green</option>' +
'<option value="Yellow">Yellow</option>';
var $severity = $(severitySting);
var $dropdown = $severity.find("select");
$dropdown.val(cellValue);
$("tr").append($severity);

take your time to read my explanation and ask me if i didn't explain myself well, thanks.
Don't mind how i print whith php, it it okay this way, this is a php setting.
i have in a template an input number that the client will fill with an amount of pallets, in the same template i have a table with as many tr as boxes the order has.
so, there are as many selects as tr, because it is used to assign the box to a pallet.
When the process is done i have the info in my database and if the client enters again he will need to have all the data in place, so the input number is filled and that fills all the selects with the amount of otions as the input, ok.
the fill process is made with jquery.
in the template, i have only this to make the select
<td><select class="pallets_assign" name="boxes[<?=$box;?>][which_pallet]"></select></td>
UPDATE:
to load the options in the selects i use this inside a document ready :
var someone = function() {
var something = function(from_pallets, to_pallets) {
var qty = $(from_pallets);
var select = $(to_pallets);
var update = function() {
select.empty();
for (var i = 1; i <= qty.val(); i++) {
select.append('<option value="' + i + '">' + i + '</option>');
}
};
qty.on('change', update);
update();
}
});
form the tamplate i call it like this:
var init = function() {
someone.something('#total_pallets', '.pallets_assign');
};
total_pallets is the id of the input number
My question is: how do i mark as selected the option which value i have stored in my database if i don't have the options created when the DOM is loaded but when that input number changed?
Thanks for your time.
Thanks to #AlonEitan to helping me find a way to solve this
in the template i had a script that did something like this:
var init = function() {
someone.something('#total_pallets', '.pallets_assign');
};
changed to:
var init = function() {
var option = [];
<? foreach ($products as $product) { ?>
<? for ($i = 1; $i <= count($product["boxes"]); $i++) { ?>
option.push(<?=(somechecks ? $product["boxes"][$i]["which_pallet"] : false);?>);
<? } ?>
<? } ?>
someone.something('#total_pallets', '.pallets_assign', option);
};
and in my js file i had this:
var someone = function() {
var something = function(from_pallets, to_pallets) {
var qty = $(from_pallets);
var select = $(to_pallets);
var update = function() {
select.empty();
for (var i = 1; i <= qty.val(); i++) {
select.append('<option value="' + i + '">' + i + '</option>');
}
};
qty.on('change', update);
update();
}
});
which is now:
var someone = function() {
var something = function(from_pallets, to_pallets, option) {
var qty = $(from_pallets);
var select = $(to_pallets);
var update = function() {
select.empty();
select.each(function(i) {
for (var j = 1; j <= qty.val(); j++) {
$(this).append('<option value="' + j + '"' + (j == option[i] ? ' selected="selected"' : '') + '>' + j + '</option>');
}
});
};
qty.on('change', update);
update();
}
});
It is a shame that in the beginning this got that many downvotes because i think is a cool way to solve this kind of issue and people will profit of this, but anyway.
My table id is "termTable". I am iterating through each row of the table. The id of textbox is "label'+ i +'" since I used for loop to generate ids randomly. The values of i will be unordered maybe after adding the rows or deleting the rows. Example: IDs are label1, label2, label3. After deleting the 2nd row, I am adding another row. So now the IDs are label1,label3, label4. I want to retrieve all the ids of all the textbox elements. How can I achieve it? Please help.
for (var i = 0; i < firstTabLength; i++) {
var row = $("#termTable tr").eq(i);
var id = row.find('input[type="text"]').attr('id'); // I could see id = undefined
}
This is Html. This is for adding the new rows to table. Guess you can visualize the table structure with the help of below code.
function AddCustomTerm1() {
len = len + 1;
var table = document.getElementById("termTable");
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
row.insertCell(0).innerHTML = '<input type="text" class="form-control" id="label' + (len - 1) + '" name="label' + (len - 1) + '" value=""><input type="hidden" id="step' + (len - 1) + '" value="1"/>';
row.insertCell(1).innerHTML = '<select class="form-control" id="dataTypes' + (len - 1) + '" name="dataTypes' + (len - 1) + '" onchange="changeDataType(this)"></select>'
row.insertCell(2).innerHTML = '<input type="text" class="form-control" id="ContractTerm' + (len - 1) + '" name="ContractTerm' + (len - 1) + '" value="">';
var DD = document.getElementById("dataTypes" + (len - 1));
for (var i = 0; i < datatypesarray.length; i++) {
var opt = document.createElement("option");
opt.text = datatypesarray[i];
opt.value = datatypesarray[i];
DD.appendChild(opt);
}
without you html format cant help much.
but try this ones.you dont even need a for loop to get all the textbox and their ids from table.
var ids=[];
$('#termTable input[type="text"]').each(function(){
ids.push($(this).attr('id'))
})
if you want ids of the textboxes in first column of the table.the try this
var ids=[];
$('#termTable tr').each(function(){
ids.push($(this).find('td:first-child input[type="text"]').attr('id'))
})
The best practice is to add a specific class to all of your elements that need to be iterated.
For example add the class term-table-input to your inputs:
row.insertCell(0).innerHTML = '<input type="text" class="form-control term-table-input" id="label' + (len - 1) + '" name="label' + (len - 1) + '" value=""><input type="hidden" id="step' + (len - 1) + '" value="1"/>';
And iterate them with:
var termTableInputIDs = [];
$('.term-table-input').each(function () {
termTableInputIDs.push($(this).attr('id'));
});
Also you could read more about writing efficient css here:
https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Writing_efficient_CSS
Since you have more than one input[type="text"] in a row, you should take the first. Also you can use each() instead of for.
$('#termTable tr').each(function() {
var id = $(this).find('input[type="text"]:first').attr('id');
console.log(id);
});
You find all the input elements inside the table by using $('#termTable input') and to loop through all the selected elements you use $.each API
Use Code like below.
var InputIds = []; //array to hold your id's
$.each($('#termTabel input[type="text"]'),function(i,v){
InputIds.push($(this).attr('id'));
});
console.log(InputIds.toString());
//this finds all inputs which id start from "label"
$('#termTable input[id^="label"]').each(function(){ console.log(this.id); });

Can you please tell me how to make list in jQuery mobile? I am trying to make this type list as given in fiddle on pop up screen dynamically .
Here is the fiddle
In this fiddle I make two rows.In first row there is only p tag. But in second row there is nested collapsible rows. I need to make same thing in pop up screen. I am able to make first row. But In my second row contend is null why? Can you suggest where I am wrong?
fiddle
$(function () {
$('#test').click(function(){
alert('d');
createCommandPopUpTabs();
$("#tabbedPopup").popup("open");
});
});
var tabsHeader = [ "InputParameter", "basic"];
var tabsHeader_basic = [ "XYZ", "Third Level",
];
function createCommandPopUpTabs(){
var header = "<h3 >dd</h3>";
var commmand = 'dd';
var button = '<button onclick="return submitCommand("'+
'")" style="" class="donebtn common-button1">Save</button>';
$("#commandInfo").append(button);
$("#commandInfoheader").html(header);
for ( var i = 0; i < tabsHeader.length; i++) {
var headerId = tabsHeader[i] + "_tab" + commmand;
var header = "<div data-role='collapsible' data-collapsed='false' id='"
+ headerId + "'><h3>InputParameter</h3></div>";
var content ;
if(tabsHeader[i]=="InputParameter"){
content = "<p>yes</p>";
}else if(tabsHeader[i]=="basic"){
for ( var i = 0; i < tabsHeader_basic.length; i++) {
headerId = tabsHeader_basic[i] + "_tab" + commmand;
header = "<div data-role='collapsible' data-collapsed='false' id='"
+ headerId + "'><h3>basic</h3></div>";
content += getcontend(tabsHeader_basic[i]);
}
}
$("#tabbedSet").append(header);
$("#tabbedSet").find("#" + headerId).append(content);
$("#tabbedSet").collapsibleset("refresh");
}
}
function getcontend(name){
if(name=="Third Level"){
return"<p>Third Level></p>";
} if(name=="XYZ"){
return"<p> second Level></p>";
}
}
There are errors in your code and logic. I will only go over a couple of them to hopefully get you on the right path:
In tabsHeader_basic array the Third Level has a space in it which you later use as an ID which makes it an invalid ID because you cannot have spaces in an ID.
From the HTML 5 Draft:
The value must not contain any space characters.
Also, the "basic" collapsible div needs to exist before you start adding the nested collapsible div.
So this line needs to come out of the for loop
header = "<div data-role='collapsible' data-collapsed='false' id='"+ headerId + "'><h3>basic</h3></div>";
Go through the JSFiddle and compare your code agaisnt my changes.
Hopefully that helps! Let me know if you have any other questions.
I have updated createCommandPopUpTabs() function.
Also removed space in Third Level on var tabsHeader_basic = ["XYZ", "ThirdLevel"];
Check the Updated Fiddle
function createCommandPopUpTabs() {
var header = "<h3 >dd</h3>";
var commmand = 'dd';
var button = '<button onclick="return submitCommand("' +
'")" style="" class="donebtn common-button1">Save</button>';
$("#commandInfo").html(button);
$("#commandInfoheader").html(header);
$("#tabbedSet").html('');
for (var i = 0; i < tabsHeader.length; i++) {
var headerId = tabsHeader[i] + "_tab" + commmand;
var header = "<div data-role='collapsible' data-collapsed='true' id='" + headerId + "'><h3>" + tabsHeader[i] + "</h3></div>";
$("#tabbedSet").append(header);
var content;
if (tabsHeader[i] == "InputParameter") {
content = "<p>yes</p>";
$("#tabbedSet").find("#" + headerId).append(content);
} else if (tabsHeader[i] == "basic") {
for (var j = 0; j < tabsHeader_basic.length; j++) {
var headerId1 = tabsHeader_basic[j] + "_tab" + commmand;
var header1 = "<div data-role='collapsible' data-collapsed='true' id='" + headerId1 + "'><h3>" + tabsHeader_basic[j] + "</h3></div>";
var content1 = getcontend(tabsHeader_basic[j]);
$("#tabbedSet").find("#" + headerId).append(header1);
$("#tabbedSet").find("#" + headerId1).append(content1);
}
}
$("#tabbedSet").collapsibleset("refresh");
}
}
I have created a depending on radio button click listbox will display now if user click a one radio button listbox will display and again user select other option but its not clear a previous value of listbox how to clear it by javascript????
<script language="JavaScript" type="text/javascript">
function fun(s)
{
if(s==B)
{
document.getElementById("maingroup").style.display='none';
document.getElementById("subgroup").style.display='';
document.getElementById("itemname").style.display='none';
}
if(s==C)
{
document.getElementById("maingroup").style.display='none';
document.getElementById("subgroup").style.display='none';
document.getElementById("itemname").style.display='';
}
</script>
Here is the example which i have tried JS FIDDLE
Try this:
var listBox = document.getElementById("listboxID");
listBox.innerHTML = "";
I think show/hide method is not good for programming.
I dont know whether it is useful or not but this might be helpful to you.
You can make it dynamic like
var mainGroup = ["aa","bb","cc"];
var subGourp = ["dd","ee","ff"];
var itemName = ["gg","ee","ff"];
var Country = ["jj","hh","ii"];
var Zone = ["kk","ll","mm"];
if(s == A)
{
var i=0;
var str = "";
for(i=0;i<mainGroup.length;i++)
{
str += "<option value='" + (i+1) + "'>" + mainGroup[i] + "</option>";
}
document.getElementById("maingroup").style.display='';
document.getElementById("maingroup").innerHTML = str;
}
else if(s == B)
{
var i=0;
var str = "";
for(i=0;i<subGourp.length;i++)
{
str += "<option value='" + (i+1) + "'>" + subGourp[i] + "</option>";
}
document.getElementById("maingroup").style.display='';
document.getElementById("maingroup").innerHTML = str;
}
This is my idea(not tested). Give every your listbox a class name like class='lst'. After that when you click on a radio button just use:
`document.getElementsByClassName('lst').style.display = 'none';`
and show current listbox.
`document.getElementsByClassName('currentListboxID').style.display = 'block';`
Here is DEMO
I have a form based menu which automatically populates the select options with the contents of a primary-nav UL. It wonderfully increments the with dashes reflecting the positions of the menu.
However, it doesn't populate the with the HREFs of the links within the ULs.
This is the code that I have:
<script>
$(function() {
var options = '<option selected></option>';
$('#primary-nav').find('a').each(function () {
var text = $(this).text(),
depth = $(this).parent().parents('ul').length,
depthChar = '',
i = 1;
for (i; i < depth; i++) { depthChar += '– ';
}
options += '<option>' + depthChar + text + '</option>';
});
$('<select id=\'mobile-menu\' />').append(options).appendTo('#mobile-nav');
$("#primary-nav select").change(function() {
window.location = $(this).find("option:selected").val();
});
});
</script>
I need to somehow add the below to the above so that when clicked the selected option goes to a url, and not a url based on the displayed value;
$("#primary-nav a").each(function() {
var el = $(this);
$("<option />", {
"value" : el.attr("href"),
"text" : el.text()
}).appendTo("#primary-nav select");
});
Can anyone advise me how I can do this?
Thank you.
You can just add the value attribute in your current code:
$('#primary-nav').find('a').each(function () {
var text = $(this).text(),
href = $(this).attr('href'),
depth = $(this).parent().parents('ul').length,
depthChar = '',
i = 1;
for (i; i < depth; i++) {
depthChar += '– ';
}
options += '<option value="'+href+'">' + depthChar + text + '</option>';
});
$('<select id=\'mobile-menu\' />').append(options).appendTo('#mobile-nav');
