i have created a dynamic jquery split button listview on a clickable button whose structure is something like this:
var Book="Book Item"
var data="hi";
//Create the listview if not created
if(!listCreated){
$("#content").append("<ul id='list' data-role='listview' data-inset='true'></ul>");
listCreated = true;
$("#content").trigger("create");
}
$("#list").append("<li data-theme='d'>"+"<a id='list_content' data-rel='popup' data-position-to='window' data-transition='pop'>"+data+"</a>"+"<a id='list_content_checkout' data-rel='popup' data-position-to='window' data-transition='pop'></a>"+"</li>");
$("#list").listview("refresh");
$("#list_content").click(function(){
alert();//
});
in given below line data is a variable whose value i want on list view click.
$("#list").append("<li data-theme='d'>"+"<a id='list_content' data-rel='popup' data-position-to='window' data-transition='pop'>"+data+"</a>"+"<a id='list_content_checkout' data-rel='popup' data-position-to='window' data-transition='pop'></a>"+"</li>");
when we click on ANKUR listview data, in alert ankur should come.
sorry for my english.
thanks
$(document).ready(function () {
Getdata();
});
function Getdata() {
var htmlcontent = "";
var strord_key = "1234";
htmlcontent += "<li data-role='list-divider'><br>";
htmlcontent += "<a href='javascript:void(0);' onclick= goToNext('" + strord_key + "') >Order Ticket: " + strord_key + "</a> </li>";
$("#result-listview").empty();
$('#result-listview').append(htmlcontent);
}
function goToNext(value) {
alert(value);

I am new to javascript. I try counting the number of clicking times by using closure.
The code is to show how many times the user clicks on the button, but it shows nothing after clicks.
html body code:
<button id="clickme">Click me!</button>
<div id="message"></div>
js code:
window.onload = function () {
var button = document.getElementById("clickme");
button.onclick = handleClick;
};
function handleClick() {
var count = 0;
var msg = "You clicked me ";
var div = document.getElementById("message");
function clicker() {
count++;
div.innerHTML = msg + count + " times.";
}
return clicker;
}
In order to make onclick to use the clicker function returned by the function handleClick, you should invoke the handleClick function.
This type of pattern is also called IIFE (Immediately-Invoked Function Expression).
window.onload = function () {
var button = document.getElementById("clickme");
button.onclick = handleClick();
};
I am working on WebGrid of MVC with jquery,
Here in my grid, there is comment column which has more text in it which is creating a scroll.
I want to give a show more or show less link in this grid.
How Can I do it.
Here is my grid
I wrote a jquery function --
$('.more').each(function () {
var content = $(this).html();
if (content.length > showChar) {
var c = content.substr(0, showChar);
var h = content.substr(showChar, content.length - showChar);
var html = c + '<span class="moreellipses">' + ellipsestext + ' </span><span class="morecontent"><span>' + h + '</span> ' + moretext + '</span>';
$(this).html(html);
}
});
and to change Label text --
$(".morelink").click(function () {
if ($(this).hasClass("less")) {
$(this).removeClass("less");
$(this).html(moretext);
} else {
$(this).addClass("less");
$(this).html(lesstext);
}
$(this).parent().prev().toggle();
$(this).prev().toggle();
return false;
});
and finally, I added .more class in WebGrid.
grid.Column("outBoundMoveOrder.Comment", header: "Comment", style: "more"),
Happy Learning !!
I have a page where I am adding jquery-ui autocompletes dynamically
My .autocomplete() code includes a $.getJSON('my_url', my_payload) where, in my_payload,' I am trying to send the request.term (what I typed into the jqueryui textbox) as well as the id of the jquery ui text box.
The problem is, for all the dynamically added textboxes, they were just picking up the term and id of the original autocomplete.
I managed to find a way to get the id of the added (not original) autocomplete by wrapping the autocomplete in a function that has the added field passed in as a parameter, but because the 'term' is in the request, which comes from .autocomplete, I do not know how to get this for the new ones.

You may want to try to make it more simple for testing. Something like:
function make_autocomplete(obj) {
obj.autocomplete({
minLength: 2,
source: function(req, resp) {
var myData = {
term: req.term,
original_form_branch_id: $(this).closest("form").attr("id"),
this_formset_row_branch_sym_id: $(this).closest(".row").find("select").val()
}
$.getJSON("myurl", myData, function(results) {
resp(results);
});
}
});
}
Fiddle: https://jsfiddle.net/Twisty/pywb9nhv/23/
This uses .closest() to gather details from the relative objects. Also I do not see any benefit to initializing Autocomplete on focus event.
If you would like further help, please provide Example Data that can be used in a working example.
Hope that helps a little.
Im using devexpress Html.DevExpress().ValidationSummary in my mvc project. My form contains a devexpress page control with 3 tabs. When there are client-side validation errors validation summary shows them, and every error is hyperlink. If you click it, the field with error is focused, but if the field is on other tab nothing happens. So the field is focused if it is on active tab. I'd like it to change the active tab and focus appropriate field. Is there a way to make it work right?
My colleague solved this problem using javascript and jQuery:
var nameControlTab = "myPageControl"; //name of your pagecontrol here
$(document).ready(function () {
$("tbody").on('click', 'a[href*="javascript:_aspxVSOnErrorClick("]', function () {
var url = $(this).attr("href");
url = url.substring(url.indexOf("'") + 1);
url = url.substring(0, url.indexOf("'"));
var idTab = $("#" + url + "_ET").parents('div[id*="' + nameControlTab + '_C"]').not(nameControlTab + '_CC')[0].id;
var indexTab = idTab.substring((nameControlTab + '_C').length);
SetTab(indexTab);
return true;
});
});
function indexOf(array, value) {
if ([].indexOf)
return array.indexOf(value);
else {
for (var i = 0; i < array.length; i++)
if (array[i] == value)
return i;
return -1;
}
}
function SetTab(indexTab) {
this[nameControlTab].SetActiveTabIndex(indexTab);
}
i got a big problem with jquery and the postback.
i'm dynamically adding html elements to my page. e.g. JQuery UI Tabs.
but after postback ALL dynamically added elements are gone.
how can i keep all of these elements after postback and also the values of textboxes and datetimepicker?

EDIT:
e.g. i'm adding some JqueryUI Tabs with this code:
$(function () {
var $tab_title_input = $("#tab_title"),
$tab_content_input = $("#tab_content");
var tab_counter = 1;
var $addButton = $('<li class="ui-state-default ui-corner-top add-button"><span>+</span></li>');
$addButton.click(function () { addTab(); });
var $tabs = $("#tabsTravel, #tabsWork").tabs({ autoHeight: true, fillSpace: true,
tabTemplate: "<li><a href='#{href}'>#{label}</a> <span class='ui-icon ui-icon-close'>Remove Tab</span></li>",
add: function (event, ui) {
var tab_content = $tab_content_input.val() || "Tab " + tab_counter + " content.";
$(ui.panel).append("<p>" + tab_content + "</p>");
$("#tabsTravel ul.ui-tabs-nav").append($addButton);
}
});
$("#tabsTravel ul.ui-tabs-nav").append($addButton);
// actual addTab function
function addTab() {
tab_counter++;
var tab_title = "worker " + tab_counter;
$tabs.tabs("add", "#tabsTravel-" + tab_counter, tab_title)
.tabs("select", "#tabsWork-" + tab_counter, tab_title);
}
// close icon: removing the tab on click
$("#tabsTravel span.ui-icon-close").live("click", function () {
var index = $("li", $tabs).index($(this).parent());
$tabs.tabs("remove", index);
tab_counter--;
});
$("#tabsWork span.ui-icon-close").live("click", function () {
var index = $("li", $tabs).index($(this).parent());
$tabs.tabs("remove", index);
// tab_counter--;
});
$('#button').click(function () {
addTab()
});
});
how can i implement this localStorage to this code?

Normally this would be the job of your server-side code; you would save the added elements in the the session cache, or in the database if the changes need to be permanent.
You could also consider using the new HTML5 session storage, or local storage, but this approach will probably be more of a hassle; best to use the sophisticated server-side libraries of PHP, .NET, etc, if possible.
Edit
Here's a simple example. Let's say your client script adds some HTML to the page:
var html = "<div>hello world</div>";
$("body").append(html);
Now, you can save it in local storage like this:
localStorage.setItem("dynamichtml", html);
If you put something in your page startup script like this:
$(document).ready(function() {
if (localStorage["dynamichtml"]) {
$("body").append(localStorage["dynamichtml"]);
}
});
Then you will have achieved the dynamic functionality. Note that the localStorage data will remain saved until the user deletes it explicitly.
