I am referring to another question display select options based on previous selections
I have while loop to fill the var data and inside a foreach loop to give the sub-menu and all work fine, var data = {'B|1':['B5|1','B4|2']
now after displaying menu1 How do I display second one, am just stopped there.
my code is:
for (var i in data) {
var ii = i.split('|');
$('#menu1').append('<option value=' + ii[1] + '>' + ii[0] + '</option>');
}
$('#menu1').change(function () {
var key = $(this).val();
$('#menu2').empty();
for (var i in data[key]) {
var ii = data[key][i].split('|');
$('#menu2').append('<option value=' + ii[1] + '>' + ii[0] + '</option>');
}
}).trigger('change');
menu1 is ok, now I need to show #menu2 with the value and text ??
This may help you
$('#menu1').change(function() {
var key = $(this).val();
var keyText = $('#menu1 :selected').text();
$('#menu2').empty();
for (var i in data[keyText +"|" + key]) {
var ii=data[keyText +"|" + key][i].split('|');
$('#menu2').append('<option value='+ii[1]+'>' + ii[0] + '</option>');
}
}).trigger('change');

I wrote this code and it works:
function getJsonResult(retrieve) {
var result = retrieve.results;
for (var i = 0; i < result.length; i++) {
responseJson.push({ id: result[i].id, title: result[i].title });
var search = '<a id="' + result[i].id + '">' + result[i].title + '</a><br/>';
document.write(search);
}
}
When I tried to display the results in a div, I change the last line with:
$("#divId").html(search);
But it only displays the first result. How can I make the whole list appear?
That happened because you're overriding the search variable in every iteration :
var search = '<a id="' + result[i].id + '">' + result[i].title + '</a><br/>';
You need to declare the search variable outside of the loop then append the string in every iteration like :
function getJsonResult(retrieve) {
var result = retrieve.results;
var search = "";
___________^^^^
for (var i = 0; i < result.length; i++) {
responseJson.push({ id: result[i].id, title: result[i].title });
var search += '<a id="' + result[i].id + '">' + result[i].title + '</a><br/>';
___________^^
document.write(search);
}
}
Then finally you could put your variable content to the div :
$("#divId").html(search);
$('#divId').append(search);
This appends the element included in search to the div element.
I want add "All" option to the existing dropdown as a first option. Pls help me
if(own != null)
{
var ar = own.replace("[","").replace("]","").split(",");
var output = $("#status_type");
output.empty();
for(var i=0;i<ar.length/2;i++)
{
output.append("<option value='" + $.trim(ar[i*2+1]) + "'>" + $.trim(ar[i*2+1]) + "</option>");
//alert ("val " +$.trim(ar[i*2+1]));
}
}
I want "All" to be the first option in select dropdown
Instead of empty() use .html() and pass the html of the All Option. This will clear the select first then will add all option and then will add other options, and will save you an unnecessary .empty() operation.
if(own != null)
{
var ar = own.replace("[","").replace("]","").split(",");
var output = $("#status_type");
output.html('<option value="'+all+'">All</option>');
for(var i=0;i<ar.length/2;i++)
{
output.append("<option value='" + $.trim(ar[i*2+1]) + "'>" + $.trim(ar[i*2+1]) + "</option>");
//alert ("val " +$.trim(ar[i*2+1]));
}
Try this: You can add ALL option just right after emptying the output variable as shown below -
if(own != null)
{
var ar = own.replace("[","").replace("]","").split(",");
var output = $("#status_type");
output.empty();
output.append("<option value='ALL'></option");//add here
for(var i=0;i<ar.length/2;i++)
{
output.append("<option value='" + $.trim(ar[i*2+1]) + "'>" + $.trim(ar[i*2+1]) + "</option>");
//alert ("val " +$.trim(ar[i*2+1]));
}
}
Try this:
$('#mysampledropdown').empty();
$.each(response.d, function(key, value) {
$("#mysampledropdown").append($("<option></option>").val(value.ID).html(value.text));
});
$('<option>').val("").text('--ALL--').prependTo('#mysampledropdown');
In below context menu example .. how to get value of fist column that invoked it?
Refer Link
tried with $(this).find('td:first').text() but it didnt work.
How to do this?
In your case you can do this:
menuSelected: function (invokedOn, selectedMenu) {
var value = invokedOn.parent().children(':first').text();
var msg = "You selected the menu item '" + selectedMenu.text() +
"' on the value '" + value + "'";
alert(msg);
}
Demo: http://jsfiddle.net/X9tgY/402/
here its working
var arr = [];
$("#myTable tr").each(function(){
arr.push($(this).find("td:first").text()); //put elements into array
});
alert(arr);
Consider this code:
invokedOn.closest('table').find('tr td:first').text()
Complete code:
menuSelected: function (invokedOn, selectedMenu) {
var msg = "You selected the menu item '" + selectedMenu.text() +
"' on the value '" + invokedOn.closest('table').find('tr td:first').text() + "'";
alert(msg);
}

Here's my code for gathering titles/posts from reddit's api:
$.getJSON("http://www.reddit.com/search.json?q=" + query + "&sort=" + val + "&t=" + time, function (data) {
var i = 0
$.each(data.data.children, function (i, item) {
var title = item.data.title
var url = item.data.url
var id = item.data.id
var subid = item.data.subreddit_id
var selftext = item.data.selftext
var selftextpost = '<p id="post' + i + '">' + selftext + '</p><br>'
var post = '<div>' + '' + title + '' + '</div>'
results.append(post)
results.append(selftextpost)
i++
});
});
Basically every post (selftext) is assigned a different paragraph id (post0, post1, post2, etc) for every result that's pulled. I'm also going to create a "hide" button that follows the same id scheme based on my i variable (submit0, submit1, submit2, etc). I want to write a function so that based on which button they click, it will hide the corresponding paragraph. I've tried doing an if statement that's like if("#hide" + i) is clicked, then hide the corresponding paragraph, but obviously that + i doesn't work. How else can I tackle this?
Could you try something like the below?
showhide = $("<a class='hider'>Show/Hide</a>");
results.append(showhide);
$(showhide).click(function() {
$(this).next().toggle();
}
Alternatively:
$.each(data.data.children, function (i, item) {
var title = item.data.title
var url = item.data.url
var id = item.data.id
var subid = item.data.subreddit_id
var selftext = item.data.selftext
var selftextpost = '<p id="post' + i + '">' + selftext + '</p><br>'
var showhide = $("<a class='hider" + i + "'>Show/Hide</a>");
var post = '<div>' + '' + title + '' + '</div>'
results.append(post)
results.append(selftextpost)
results.append(showhide);
$(showhide).click(function() {
$(this).next().toggle();
});
i++
});
I have some onchange events setup in jQuery which are used to populate a select dropdown boxbased on what is selected in another select dropdown.
I need these to also run on page load that so that results are returned based on what the first select box is at on page load (otherwise I end up with an empty select box). I've had a look around the internets but can't find anything that fits exactly what I want to do
My jQuery code is
$(function(){
//Get Contacts for Company
$("select#ContactCompanyId").change(function(){
var url = "contactList/" + $(this).val() + "";
$.getJSON(url,{id: $(this).val(), ajax: 'true'}, function(j){
var options = '';
$.each(j, function(key, value){
options += '<option value="' + key + '">' + value + '</option>';
})
$("select#QuoteContactId").html(options);
})
})
//Get list of product Categories
$("select#ProductCategory").live('change', function(){
var url = "productList/" + $(this).val() + "";
var id = $(this).attr('name');
$.getJSON(url,{id: $(this).val(), ajax: 'true'}, function(j){
var options = '';
options += '<option value="0">None</option>';
$.each(j, function(key, value){
options += '<option value="' + key + '">' + value + '</option>';
})
$("select#QuoteItem" + id + "product_id").html(options);
})
})
//Function to add product data into the form
$(".Product").live('change', function(){
var url = "productData/" + $(this).val() + "";
var id = $(this).attr('title');
$.getJSON(url,{id: $(this).val(), ajax: 'true'}, function(j){
$("#QuoteItem" + id + "name").val(j['Product']['name']);
$("#QuoteItem" + id + "price").val(j['Product']['price']);
$("#QuoteItem" + id + "description").val(j['Product']['description']);
})
})
})
Thanks in advance for your help
You can just trigger the event just after binding it with .trigger() like this:
$("select#ContactCompanyId").change(function(){
var url = "contactList/" + $(this).val() + "";
$.getJSON(url,{id: $(this).val(), ajax: 'true'}, function(j){
var options = '';
$.each(j, function(key, value){
options += '<option value="' + key + '">' + value + '</option>';
})
$("select#QuoteContactId").html(options);
});
}).trigger('change');
$(document).ready(function() {
$('#your_select_id').change();
});
This fires the change event for your select, with its current value. Its the equivlent of a user selecting the current value, and it will fire any events attached to it that would fire from an onchange event.
