Its my first time using the tooltip and have done a lot research on it. I used the jquery website to get most of the information. I intend my tooltip to show dynamic data when a mouse clicks the hyperlink. I added the title to my link and have this code below:
var t = 1000;
$(document).tooltip({
content: '... waiting on ajax ...',
open: function(evt, ui) {
var elem = $(this);
$.ajax({ type: "POST",url:'/GetTooltip/', data: 80140}).always(function() {
elem.tooltip('option', 'content', 'Ajax call complete');
});
setTimeout(function(){
$(ui.tooltip).hide('destroy');
}, t);},
position: {
my: "center bottom-20",
at: "center top",
using: function( position, feedback ) {
$( this ).css( position );
$( "<div>" )
.addClass( "arrow" )
.addClass( feedback.vertical )
.addClass( feedback.horizontal )
.appendTo( this );
}
}
});
I am not fully knowledgeable with the syntax of the ajax call in reference to the always function and how to get the data to show on my tooltip. the GetTooltip returns JSON data, I just want to post to the GetTooltip script and the returned data to show on my tooltip. At the moment my ajax is posting nothing.
Regarding your statement that you are not fully knowledgeable with
always function: the always(function(data|jqXHR, textStatus, jqXHR|errorThrown) { }); is always executed after the ajax request was executed. For more see the documentation deferred.always() Please look also at jqXHR.always(function(data|jqXHR, textStatus, jqXHR|errorThrown) { })
get the returned data to show on the tooltip - see the example in the fiddle
You can find many other answers on stackoverflow. Take a look at this fiddle and let me know if you need more help.
Updated fiddle 2
If have updated the fiddle. You can pass values from the parameters that are returned from the ajax callback. This is a simple wrapper around the ajax call:
function callAjax(elem){
$.ajax({ url: '/echo/json/',
type: 'POST',
contentType:"application/json; charset=utf-8",
dataType:"json",
data: { json: JSON.stringify({ text: 'some text'})}
}).always(
function(data,textStatus, errorThrown)
{
elem.tooltip('option', 'content'
, 'Ajax call complete. Result:' + data.text);
});
}
I am using JSON.stringify(...) above to create a Json-String. This function may be not present in all browsers. So if you run into troubles please use a current chrome / chromium browser to test it.
So you can use the wrapper function inside the tooltip():
$('#tippy').tooltip({
content: '... waiting on ajax ...',
open: function(evt, ui) {
var elem = $(this);
callAjax(elem);
} // open
});
Above you can see that the always method calls an anonymous function with 3 parameters (data, textStatus, errorThrown). To pass the reply from the ajax call you can use data. Above i am only passing a simple object with the propert text. To access it you can use data.text

I added data to the page in Ajax and then I changed to the page
$.mobile.changePage('#postDetails', { transition: "slide" })
but then when I refresh the browser all the contents I added with the Ajax is not there any more.
refreshing a page will remove Ajax data, to resolve that issue you need to add your Ajax call inside pageshow event like following
$(document).on("pageshow","#postDetails",function(){
$.ajax({
url: postDetailsUrl,
type: "post",
data: {id: id},
beforeSend: function () {
$.mobile.loading("show");
},
complete: function () {
$.mobile.loading("hide");
},
success: function (data) {
$('#commentList').html(data);
$('#commentsNum').text($('#commentList .comment').length);
initCommentPage();
},
error: function (requestObject, error, errorThrown) {
alert("Error in communication");
}
});
})
now this ajax request is in pageshow event so every time popstDetails page is shown it will make a ajax call to postDetailsUrl and show the data in commentList element.

We currently have two HTML textareas 'tinput'(primary) and 'toutput' (secondary) where we mimic the input in the primary to be reflected in the secondary as if someone is really typing in the secondary. The idea is to trigger an 'autocomplete' (over ajax) on the secondary. We have this working but not optimally.
We have attached a JQuery UI 'Autocomplete' (JQAC) to the secondary with a minLength:3 set. You may know that, normally, after 3 characters have been entered, JQAC 'buffers' the char entries thereon after and doesn't make an ajax call for every char that has been entered. Which is ideal.
However, with our secondary mimicking we have subverted this behavior, unfortunately, where after the 3rd char entry a JQAC ajax call is being made for every char after-- which is not optimal. We know why but don't know how to get around it. We believe we've subverted this because we are calling
$('#tinput').autocomplete('search',$('#tinput').val())
in the secondary's key handle, which by JQAC's documentation forces an ajax call.
To summarize, we need the secondary, that has JQAC attached to it, to behave as if someone were really typing into it and the JQAC behaving normally.
Here is JS for what we have as our char input mimic handling(we've changed variable names for this post so please ignore typos):
$("#tinput").on('input', function (e) {
$("#toutput").val($("#tinput").text());
var newEvent = jQuery.Event("keypress");
newEvent.which = e.which; // # Some key code value
$("#toutput").trigger(newEvent);
});
$("#toutput").keypress(function(e) {
$("#toutput").autocomplete('search',$("#toutput").val());
});
$( "#tinput" ).autocomplete({
appendTo: "#modalparent",
source: function( request, response ) {
$.ajax({
url: "https://xxxxxx",
type: "POST",
dataType: "json",
data: JSON.stringify({ "ourterm": request.term}),
success: function( data ) {
response( $.map( data.data.suggestions, function( item ) {
return {
label: item,
value: item
};
}));
}
});
},
minLength: 3,
select: function( event, ui ) {
// console.log( ui.item ?
// "Selected: " + ui.item.label :
// "Nothing selected, input was " + this.value);
},
open: function() {
$( this ).removeClass( "ui-corner-all" ).addClass( "ui-corner-top" );
},
close: function() {
$( this ).removeClass( "ui-corner-top" ).addClass( "ui-corner-all" );
}
});
Any thoughts would be appreciated. Thanks!
We have found an elegant solution. It was a minor modification to our original.
change the trigger event by the primary to 'input' instead of the original 'keypress'.
remove the handler for the secondary.
here is the updated JS:
$("#tinput").on('input', function (e) {
$("#toutput").val($("#tinput").text());
var newEvent = jQuery.Event("input");
newEvent.which = e.which; // # Some key code value
$("#toutput").trigger(newEvent);
});
and delete:
//$("#toutput").keypress(function(e) {
// $("#toutput").autocomplete('search',$("#toutput").val());
// });
DONE.
Friends I have a problem
We need to make a user control that has the ability to delete itself, I made it but we did not clear the mechanism for removal, it should be tied to a nice picture. Code that is attached to the frame is given below, but not
$('#delete').bind('click', function () {
alert('test');
var urlA = '<%=Url.Action("DeleteMessage","Ticket")%>';
$.ajax({
url: urlA,
type: 'POST',
data: { idMessage:$(this).parents("div:first").find("input[name='MessageID']").val(),idticket:$('#TicketID').val() },
success: function (data) {
alert(data);
}
});
});
But when I write this, but to throw me to the homepage what's wrong
$('#delete').live('click', function ()
$("#delete").live("click", function(){
//code
$(this).remove(); //delete itself
});
If your image is declared as input type="image" then it will behave like a submit button and submit your page. You should prevent the default behavior of submitting the page by adding an event.preventDefault() or equivalent to your javascript function.
Why, if i write html method in javascript, it's called only once, but if i have only alert, it's calles every time, i change wy value in input (blur).
$(".quantity").blur(function() {
console.log("upd");
$.ajax({
url: "/line_items/update_quantity/"+$(this).attr("id"),
type: "GET",
data: {quantity: $(this).val()},
success: function(text)
{
alert(text);
$('.right').html(text);
},
error: function(){
alert('Ошибка javascript');
},
dataType : "html"
});
});
I need reload html partial after every blur...
Try doing this..
$(document).on('blur', '.quantity', function() {
// place your code here
});
I suspect you're replacing the dom element that the original blur binding is applied against. If you do that you remove the event handler. On() will keep it alive.
If .quantity is dynamic element (I think so) then try
$(document).delegate('.quantity', 'blur', function() {
// code
});

I'm trying to use jqueryui autocmplete with amplifyjs. Thats's to be able to switch between call to real server data and some hardcoded one and for additional flexibility.
For now I do not know how to make jqueryui autocomplete call amplify to refresh itself and perform search. I have the following codesnippet:
amplify.request.define('resId', 'ajax', {
url: 'autocmpleteUrl',
dataType: "json",
type: "POST"
});
$(elementId).autocomplete({
minLength: 1,
source: 'some url',
delay: 0,
focus: function (event, ui) {
$(elementId).val(ui.item.label);
return false;
},
select: function (event, ui) {
$(elementId).val(ui.item.label);
return false;
}
}).data("autocomplete")._renderItem = function (ul, item) {
return $("<li></li>")
.data("item.autocomplete", item)
.append("<a>" + item.label + "</a>")
.appendTo(ul);
};
I know in autocomplete part it can both be url and json data. But I can't figure out how to make it deal with amplify and make it so that if user inputs text jquery autocomplete requests amplify, not the url itself. Any ideas?
That's close to what you want, but you've forgotten to pass the search term to your request. Your code should be:
$( elem ).autocomplete({
source: function( request, response ) {
amplify.request( "resId", request, function( data ) {
response( data );
});
});
});
Which will send the search term as the term query parameter. Since you're doing a direct passthrough of the data, this can also be reduced:
$( elem ).autocomplete({
source: function( request, response ) {
amplify.request( "resId", request, response );
});
});
However, in both of these cases you're not handling errors, which means that you can leave the autocomplete in the search state indefinitely. You should use the full amplify.request form to handle errors:
$( elem ).autocomplete({
source: function( request, response ) {
amplify.request({
resourceId: "resId",
data: request,
success: response,
error: function() {
response( [] );
}
});
});
});
I've completed with the following solution:
autocomplete({
source: function(request, response){
amplify.request('resId', function(data){
response(data);
});
},
So you can provide a function to jquery.ui autocomplete and in this function just set the request object and autocomplete data will be filled with data you provide.
