I have a masked input I'm trying to build and it works fine in Chrome, only in firefox it doesn't update my text field with the new value...
I receive no console errors neither so I'm unsure what the problem could be?
$('.new-Btn').bind("click", function () {
$('.html-btn').click();
});
$('.html-btn').change(function () {
var newval = $('.html-btn').val();
var nvstr = newval.substring(12, 25);
$('.new-Btn').html(nvstr);
});
http://jsfiddle.net/ykgXG/
The problem was with browser agents.Some browser displays full path name(chrome,opera,explorer) where as some does not(mozilla).
Here is the code:
var nvstr;
var newval;
$('.html-btn').on('change',function () {
newval = $('.html-btn').val();
if(!$.browser.mozilla){
nvstr = newval.substring(12, 25);
$('.new-Btn').html(nvstr);
}else{
alert(11)
$('.new-Btn').html(newval);
}
});
Here is a working demo:http://jsfiddle.net/ykgXG/8/
Tested in all the browsers and it works.
u shd use:
$('.new-Btn').bind("click", function () {
$('.html-btn').trigger('click');
});
$('.html-btn').change(function () {
var newval = $('.html-btn').val();
var nvstr = newval.substring(12, 25);
$('.new-Btn').html(nvstr);
});
What I am seeing is that your div text changes under Firefox 24. Check what your substring() function returns with the file that you're testing it with.
As my issue was with the fakepathprefix I used an if statement to fun a different function dependant on the browser.
if (/chrom(e|ium)/.test(navigator.userAgent.toLowerCase())) {
$('.new-Btn').bind("click", function () {
$('.html-btn').trigger('click');
});
$('.html-btn').change(function () {
var newval = $('.html-btn').val();
var nvstr = newval.substring(12, 25);
$('.new-Btn').html(nvstr);
});
} else {
$('.new-Btn').bind("click", function () {
$('.html-btn').trigger('click');
});
$('.html-btn').change(function () {
var newval = $('.html-btn').val();
$('.new-Btn').html(newval);
});
}

I try to resize an iframe with jQuery and JS. First I get the iframe out of a list of iframes and resize it when the iframe-content is ready.
NOTE: The two-steps resize is necessary because otherwise after the
content of the iframe-page is a huge space.
Problem: In the while-loop I check if the content of the iframe is ready, when not I set a timeout of 1 second. But jQuery don’t check if the content ready it always goes inside the if and try to resize the iframe but fails because jQuery cannot get the size of a NULL element.
Has someone of you a solution for my problem?
My Code:
$(document).ready(function () {
var iframes = $(".my-iframe");
$.each(iframes, function () {
resizeIframe(this);
});
});
function resizeIframe(iframe) {
$(iframe).width("100%");
var iframeIsReady = false;
do
{
if ($(iframe).ready)
{
var iframeHeight = iframe.contentDocument.body.scrollHeight;
$(iframe).height(iframeHeight);
var iframeContentHeight = $(iframe).children("#DivInPage").height();
$(iframe).height(iframeContentHeight);
iframeIsReady = true;
}
else
{
setTimeout(resizeIframe(iframe), 1000);
}
}while(!iframeIsReady);
}
Edit:
Check out my solution
Hi there is small change in your code please check following.
$(document).ready(function () {
var iframes = $(".my-iframe")[0]; // $(".my-iframe"); /Edited
$.each(iframes, function () {
resizeIframe(this);
});
});
function resizeIframe(iframe) {
$(iframe).width("100%");
var iframeIsReady = false;
do
{
if ($(iframe.contentDocument).ready) // added 'iframe.contentDocument' instead of iframe
{
var iframeHeight = iframe.contentDocument.body.scrollHeight;
$(iframe).height(iframeHeight);
var iframeContentHeight = $(iframe).children("#DivInPage").height();
$(iframe).height(iframeContentHeight);
iframeIsReady = true;
}
else
{
setTimeout(resizeIframe(iframe), 1000);
}
}while(!iframeIsReady);
}
try this.
I checked code again found that $(".my-iframe") returns array of element object.
We need object here not array.
So i hard coded 0th index. you can use id instead of this.
Solution of my problem is:
$(document).ready(function () {
var iframes = $(".my-iframe");
$.each(iframes, function () {
resizeIframe(this);
});
});
function resizeIframe(iframe) {
$(iframe).width("100%");
setInterval(function () {
//Check if the Content inside the iframe is ready
if ($(iframe.contentDocument.body).ready) {
var iframeHeight = iframe.contentDocument.body.scrollHeight;
$(iframe).height(iframeHeight);
var iframeContentHeight = $(iframe).children("#DivInPage").height();
$(iframe).height(iframeContentHeight);
//Close the Function
return;
}
}, 1000);
}
Am getting key Combination from the server. Based on that am assigning key Combination to function dynamically. The below code is working for last iteration in loop. how below code is work for all iterations.
In my page i have two buttons save and cancel the below code is working for last iteration in for loop, It means btnCanel button triggers if i press key for save function.Any suggestions. hope understand my question.
$(document).ready(function fn() {
var keyCombination = new Object();
keyCombination['btnAdd'] = "Alt+S";
keyCombination['btnCancel'] = "Alt+C";
for (var k in keyCombination) {
if (keyCombination.hasOwnProperty(k)) {
shortcut.add(String(keyCombination[k]), function () {
var btnAdd = document.getElementById(String(k));
btnAdd.focus();
btnAdd.click();
});
}
}
});
if i give like this means it is working
shortcut.add("Alt+S", function () {
var btnAdd = document.getElementById('btnAdd ');
btnAdd .focus();
btnAdd .click();
});
shortcut.add("Alt+C", function () {
var btnCancel = document.getElementById('btnCancel');
btnCancel.focus();
btnCancel.click();
});
but if i try to add dynamically its overriding help me this issue.
Thanks in Advance.
I created a separate function outside the document.ready function like this now its working fine.
$(document).ready(function fn() {
var keyCombination = new Object();
keyCombination['btnAdd'] = "Alt+S";
keyCombination['btnCancel'] = "Alt+C";
for (var k in keyCombination) {
if (keyCombination.hasOwnProperty(k)) {
Set_KeyCombinations(k, keyCombination);
}
}
});
function Set_KeyCombinations(k, keyCombination) {
shortcut.add(String(keyCombination[k]), function () {
var eleId = document.getElementById(String(k));
if (eleId) {
if ($('#' + String(k).trim()).css('display') !== 'none' && eleId.getAttribute("disabled") !== "disabled") {
eleId.click();
eleId.focus();
}
}
});
}
Try this:
var keyCombinations = [ "Ctrl+Shift+X" , "Ctrl+Shift+Y" ];
for(var i=0; i<keyCombinations.length; i++){
(function(shorcutCombination){
shortcut.add(shorcutCombination,function() {
alert("i am " + shorcutCombination);
});
})(keyCombinations[i]);
}
The idea is that you need to preserve the value of keyCombinations[i]
as i increases in the loop. Tested this here: Openjs
We all know that use the val() will not trigger the change event, so we also use .trigger('change') behind the val().
But the problem is that someone write the val() did't with trigger() and it's a external file that I can't edit it.
So, how can I detect value change through some code same like below:
$('.elem').on('change', function(){
// do something
});
My suggestion is to override jquery's val()
var originalValFn = jQuery.fn.val;
jQuery.fn.val = function() {
this.trigger('change');
originalValFn.apply( this, arguments );
}
jsfiddle: http://jsfiddle.net/2L7hohjz/js
var originalValFn = jQuery.fn.val;
function getErrorObject(){
try { throw Error('') } catch(err) { return err; }
}
jQuery.fn.val = function() {
if ($(this).hasClass( "element" )) {
var err = getErrorObject();
var caller_line = err.stack.split("\n")[4];
var index = caller_line.indexOf("at ");
var clean = caller_line.slice(index+2, caller_line.length);
console.log(clean);
console.log(arguments);
}
originalValFn.apply( this, arguments );
};
Try:
setTimeout(function() {
if (currentValue != previousValue)
{
// do something
}
}, 500);
Thank you,
I commonly use the solution from this post to get around problems like this one:
hidden input change event
watchField('.elem', function(){
//do some stuff here
});
function watchField(selector, callback) {
var input = $(selector);
var oldvalue = input.val();
setInterval(function(){
if (input.val()!=oldvalue){
oldvalue = input.val();
callback();
}
}, 100);
}
Try:
$('.elem').on('keyUp', function(){
// do something
});
or
$('.elem').on('lostFocus', function(){
// do something
});
Thank you,
I have some jQuery plugin that changes some elements, i need some event or jQuery plugin that trigger an event when some text input value changed.
I've downloaded jquery.textchange plugin, it is a good plugin but doesn't detect changes via external source.
#MSS -- Alright, this is a kludge but it works:
When I call boxWatcher() I set the value to 3,000 but you'd need to do it much more often, like maybe 100 or 300.
http://jsfiddle.net/N9zBA/8/
var theOldContent = $('#theID').val().trim();
var theNewContent = "";
function boxWatcher(milSecondsBetweenChecks) {
var theLoop = setInterval(function() {
theNewContent = $('#theID').val().trim();
if (theOldContent == theNewContent) {
return; //no change
}
clearInterval(theLoop);//stop looping
handleContentChange();
}, milSecondsBetweenChecks);
};
function handleContentChange() {
alert('content has changed');
//restart boxWatcher
theOldContent = theNewContent;//reset theOldContent
boxWatcher(3000);//3000 is about 3 seconds
}
function buttonClick() {
$('#theID').value = 'asd;lfikjasd;fkj';
}
$(document).ready(function() {
boxWatcher(3000);
})
try to set the old value into a global variable then fire onkeypress event on your text input and compare between old and new values of it. some thing like that
var oldvlaue = $('#myInput').val();
$('#myInput').keyup(function(){
if(oldvlaue!=$('#myInput').val().trim())
{
alert('text has been changed');
}
});
you test this example here
Edit
try to add an EventListner to your text input, I don't know more about it but you can check this Post it may help
Thanks to #Darin because of his/her solution I've marked as the answer, but i have made some small jQuery plugin to achieve the same work named 'txtChgMon'.
(function ($) {
$.fn.txtChgMon = function (func) {
var res = this.each(function () {
txts[0] = { t: this, f: func, oldT: $(this).val(), newT: '' };
});
if (!watchStarted) {
boxWatcher(200);
}
return res;
};
})(jQuery);
var txts = [];
var watchStarted = false;
function boxWatcher(milSecondsBetweenChecks) {
watchStarted = true;
var theLoop = setInterval(function () {
for (var i = 0; i < txts.length; i++) {
txts[i].newT = $(txts[i].t).val();
if (txts[i].newT == txts[i].oldT) {
return; //no change
}
clearInterval(theLoop); //stop looping
txts[i].f(txts[i], txts[i].oldT, txts[i].newT);
txts[i].oldT = $(txts[i].t).val();
boxWatcher(milSecondsBetweenChecks);
return;
}
}, milSecondsBetweenChecks);
}
I'm trying to build a Javascript listener for a small page that uses AJAX to load content based on the anchor in the URL. Looking online, I found and modified a script that uses setInterval() to do this and so far it works fine. However, I have other jQuery elements in the $(document).ready() for special effects for the menus and content. If I use setInterval() no other jQuery effects work. I finagled a way to get it work by including the jQuery effects in the loop for setInterval() like so:
$(document).ready(function() {
var pageScripts = function() {
pageEffects();
pageURL();
}
window.setInterval(pageScripts, 500);
});
var currentAnchor = null;
function pageEffects() {
// Popup Menus
$(".bannerMenu").hover(function() {
$(this).find("ul.bannerSubmenu").slideDown(300).show;
}, function() {
$(this).find("ul.bannerSubmenu").slideUp(400);
});
$(".panel").hover(function() {
$(this).find(".panelContent").fadeIn(200);
}, function() {
$(this).find(".panelContent").fadeOut(300);
});
// REL Links Control
$("a[rel='_blank']").click(function() {
this.target = "_blank";
});
$("a[rel='share']").click(function(event) {
var share_url = $(this).attr("href");
window.open(share_url, "Share", "width=768, height=450");
event.preventDefault();
});
}
function pageURL() {
if (currentAnchor != document.location.hash) {
currentAnchor = document.location.hash;
if (!currentAnchor) {
query = "section=home";
} else {
var splits = currentAnchor.substring(1).split("&");
var section = splits[0];
delete splits[0];
var params = splits.join("&");
var query = "section=" + section + params;
}
$.get("loader.php", query, function(data) {
$("#load").fadeIn("fast");
$("#content").fadeOut(100).html(data).fadeIn(500);
$("#load").fadeOut("fast");
});
}
}
This works fine for a while but after a few minutes of the page being loaded, it drags to a near stop in IE and Firefox. I checked the FF Error Console and it comes back with an error "Too many Recursions." Chrome seems to not care and the page continues to run more or less normally despite the amount of time it's been open.
It would seem to me that the pageEffects() call is causing the issue with the recursion, however, any attempts to move it out of the loop breaks them and they cease to work as soon as setInterval makes it first loop.
Any help on this would be greatly appreciated!
I am guessing that the pageEffects need added to the pageURL content.
At the very least this should be more efficient and prevent duplicate handlers
$(document).ready(function() {
pageEffects($('body'));
(function(){
pageURL();
window.setTimeout(arguments.callee, 500);
})();
});
var currentAnchor = null;
function pageEffects(parent) {
// Popup Menus
parent.find(".bannerMenu").each(function() {
$(this).unbind('mouseenter mouseleave');
var proxy = {
subMenu: $(this).find("ul.bannerSubmenu"),
handlerIn: function() {
this.subMenu.slideDown(300).show();
},
handlerOut: function() {
this.subMenu.slideUp(400).hide();
}
};
$(this).hover(proxy.handlerIn, proxy.handlerOut);
});
parent.find(".panel").each(function() {
$(this).unbind('mouseenter mouseleave');
var proxy = {
content: panel.find(".panelContent"),
handlerIn: function() {
this.content.fadeIn(200).show();
},
handlerOut: function() {
this.content.slideUp(400).hide();
}
};
$(this).hover(proxy.handlerIn, proxy.handlerOut);
});
// REL Links Control
parent.find("a[rel='_blank']").each(function() {
$(this).target = "_blank";
});
parent.find("a[rel='share']").click(function(event) {
var share_url = $(this).attr("href");
window.open(share_url, "Share", "width=768, height=450");
event.preventDefault();
});
}
function pageURL() {
if (currentAnchor != document.location.hash) {
currentAnchor = document.location.hash;
if (!currentAnchor) {
query = "section=home";
} else {
var splits = currentAnchor.substring(1).split("&");
var section = splits[0];
delete splits[0];
var params = splits.join("&");
var query = "section=" + section + params;
}
var content = $("#content");
$.get("loader.php", query, function(data) {
$("#load").fadeIn("fast");
content.fadeOut(100).html(data).fadeIn(500);
$("#load").fadeOut("fast");
});
pageEffects(content);
}
}
Thanks for the suggestions. I tried a few of them and they still did not lead to the desirable effects. After some cautious testing, I found out what was happening. With jQuery (and presumably Javascript as a whole), whenever an AJAX callback is made, the elements brought in through the callback are not binded to what was originally binded in the document, they must be rebinded. You can either do this by recalling all the jQuery events on a successful callback or by using the .live() event in jQuery's library. I opted for .live() and it works like a charm now and no more recursive errors :D.
$(document).ready(function() {
// Popup Menus
$(".bannerMenu").live("hover", function(event) {
if (event.type == "mouseover") {
$(this).find("ul.bannerSubmenu").slideDown(300);
} else {
$(this).find("ul.bannerSubmenu").slideUp(400);
}
});
// Rollover Content
$(".panel").live("hover", function(event) {
if (event.type == "mouseover") {
$(this).find(".panelContent").fadeIn(200);
} else {
$(this).find(".panelContent").fadeOut(300);
}
});
// HREF Events
$("a[rel='_blank']").live("click", function(event) {
var target = $(this).attr("href");
window.open(target, "_blank");
event.preventDefault();
});
$("a[rel='share']").live("click", function(event) {
var share_url = $(this).attr("href");
window.open(share_url, "Share", "width=768, height=450");
event.preventDefault();
});
setInterval("checkAnchor()", 500);
});
var currentAnchor = null;
function checkAnchor() {
if (currentAnchor != document.location.hash) {
currentAnchor = document.location.hash;
if (!currentAnchor) {
query = "section=home";
} else {
var splits = currentAnchor.substring(1).split("&");
var section = splits[0];
delete splits[0];
var params = splits.join("&");
var query = "section=" + section + params;
}
$.get("loader.php", query, function(data) {
$("#load").fadeIn(200);
$("#content").fadeOut(200).html(data).fadeIn(200);
$("#load").fadeOut(200);
});
}
}
Anywho, the page works as intended even in IE (which I rarely check for compatibility). Hopefully, some other newb will learn from my mistakes :p.
