I need help ... I have a javascript code that was written for IE10 / IE11 now I have to implement some function in Google Chrome but in code I have the function windows.showModalDialog which as I know does not work on chrome currently, I need to migrate this code so that it works on window .open, could anyone help?
function ShowContactSearch() {
var windowWidth = 800, windowHeight = 600, centerWidth = (screen.availWidth - windowWidth) / 2, centerHeight = (screen.availHeight - windowHeight) / 2 - 20;
var result = window.open('/Contact.aspx', null, 'dialogWidth:1300px; dialogHeight:720px; center:1; resizable:1; status=1');
if (result != null) {
ContactChosen(result, '1');
}
function ContactChosen(contactId, cType) {
var ct = document.getElementById("<%=hfChosenContactId.ClientID %>");
if (contactId == null || contactId == "" || ct.value == "" || contactId.toLowerCase().indexOf(ct.value.toLowerCase()) < 0) {
ct.value = contactId;
document.getElementById("<%=hfCType.ClientID %>").value = cType;
document.getElementById("<%=bChosenContactId.ClientID %>").click();
}
return false;
}

//enter a color name or hex to be used as the background color of the message

any help. or any new code please
If I'm understanding what you want, I think you're totally over thinking it. You can use CSS to keep your message fixed at the top of the page. just add position: fixed. It's how I make my header stay at the top of the page on this site: http://www.recipegraze.com
So use javascript to make the message appear/disappear, but use some simple CSS to make it stick to the top of the page.
edit: you'll also want to up the z-index of the message to make sure it appears on top of your other content, not under it.
How can I detect if Acrobat X Pro is installed on a machine using javascript. I have code that works for Adobe Reader. but now I have upgrdaed my adobe version to Acrobat X Pro. But it is not working for Acrobat X Pro using IE8.
var perform_acrobat_detection = function()

im getting a little issue here. I have a wordpress theme that i need to add an infinite scroll effect. Ok, its working, but it doesnt look work properly. I set the current page and the number of pages, but it keeps adding the second page every time i reach the bottom.
What im doing wrong?
Ps.: I have tried the inifite-scroll plugin for wordpress, and it dont works with my template. Thanks!
$(function() {
var currentPage = 1;
var numPages = Math.ceil(pages / 4);
var browserName = "";
var ua = navigator.userAgent.toLowerCase();
if (ua.indexOf("opera") != -1) {
browserName = "opera";
} else if (ua.indexOf("msie") != -1) {
browserName = "msie";
} else if (ua.indexOf("safari") != -1) {
browserName = "safari";
} else if (ua.indexOf("mozilla") != -1) {
if (ua.indexOf("firefox") != -1) {
browserName = "firefox";
} else {
browserName = "mozilla";
}
}
$(window).scroll(function() {
if (browserName != "safari") {
var curScrollPos = $('html').scrollTop();
}
else {
var curScrollPos = $('body').scrollTop();
}
if (curScrollPos > 218) {
$("#sidebar").addClass("open");
}
if (curScrollPos < 218) {
$("#sidebar").removeClass("open");
}
var scrollBottom = $(document).height() - $(window).height() - $(window).scrollTop();
if (scrollBottom == 0) {
if (currentPage < numPages) {
$("<div>").load("page/" + (currentPage + 1), function() {
var newPosts = $(this).find("#content").html();
$("#content").append(newPosts);
});
currentPage++;
}
else {
}
}
});
// Infinite Scroll
});
Possibly try this:
$("<div>").load("page/"+(currentPage+1), function() {
var newPosts = $(this).find("#content").html();
$("#content").append(newPosts);
currentPage++;
});
And remove the currentPage++;
Though both are Webkit based browsers, Safari urlencodes quotation marks in the URL while Chrome does not.
Therefore I need to distinguish between these two in JS.
jQuery's browser detection docs mark "safari" as deprecated.
Is there a better method or do I just stick with the deprecated value for now?
Using a mix of feature detection and Useragent string:
var is_opera = !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0;
var is_Edge = navigator.userAgent.indexOf("Edge") > -1;
var is_chrome = !!window.chrome && !is_opera && !is_Edge;
var is_explorer= typeof document !== 'undefined' && !!document.documentMode && !is_Edge;
var is_firefox = typeof window.InstallTrigger !== 'undefined';
var is_safari = /^((?!chrome|android).)*safari/i.test(navigator.userAgent);
Usage:
if (is_safari) alert('Safari');
Or for Safari only, use this :
if ( /^((?!chrome|android).)*safari/i.test(navigator.userAgent)) {alert('Its Safari');}
The following identifies Safari 3.0+ and distinguishes it from Chrome:
isSafari = !!navigator.userAgent.match(/Version\/[\d\.]+.*Safari/)
unfortunately the above examples will also detect android's default browser as Safari, which it is not.
I used
navigator.userAgent.indexOf('Safari') != -1 && navigator.userAgent.indexOf('Chrome') == -1 && navigator.userAgent.indexOf('Android') == -1
For checking Safari I used this:
$.browser.safari = ($.browser.webkit && !(/chrome/.test(navigator.userAgent.toLowerCase())));
if ($.browser.safari) {
alert('this is safari');
}
It works correctly.
Apparently the only reliable and accepted solution would be to do feature detection like this:
browser_treats_urls_like_safari_does = false;
var last_location_hash = location.hash;
location.hash = '"blah"';
if (location.hash == '#%22blah%22')
browser_treats_urls_like_safari_does = true;
location.hash = last_location_hash;
The only way I found is check if navigator.userAgent contains iPhone or iPad word
if (navigator.userAgent.toLowerCase().match(/(ipad|iphone)/)) {
//is safari
}
If you are checking the browser use $.browser. But if you are checking feature support (recommended) then use $.support.
You should NOT use $.browser to enable/disable features on the page. Reason being its not dependable and generally just not recommended.
If you need feature support then I recommend modernizr.
//Check if Safari
function isSafari() {
return /^((?!chrome).)*safari/i.test(navigator.userAgent);
}
//Check if MAC
if(navigator.userAgent.indexOf('Mac')>1){
alert(isSafari());
}
http://jsfiddle.net/s1o943gb/10/
This will determine whether the browser is Safari or not.
if(navigator.userAgent.indexOf('Safari') !=-1 && navigator.userAgent.indexOf('Chrome') == -1)
{
alert(its safari);
}else {
alert('its not safari');
}
I use to detect Apple browser engine, this simple JavaScript condition:
navigator.vendor.startsWith('Apple')
A very useful way to fix this is to detect the browsers webkit version and check if it is at least the one we need, else do something else.
Using jQuery it goes like this:
"use strict";
$(document).ready(function() {
var appVersion = navigator.appVersion;
var webkitVersion_positionStart = appVersion.indexOf("AppleWebKit/") + 12;
var webkitVersion_positionEnd = webkitVersion_positionStart + 3;
var webkitVersion = appVersion.slice(webkitVersion_positionStart, webkitVersion_positionEnd);
console.log(webkitVersion);
if (webkitVersion < 537) {
console.log("webkit outdated.");
} else {
console.log("webkit ok.");
};
});
This provides a safe and permanent fix for dealing with problems with browser's different webkit implementations.
Happy coding!
// Safari uses pre-calculated pixels, so use this feature to detect Safari
var canva = document.createElement('canvas');
var ctx = canva.getContext("2d");
var img = ctx.getImageData(0, 0, 1, 1);
var pix = img.data; // byte array, rgba
var isSafari = (pix[3] != 0); // alpha in Safari is not zero
Generic FUNCTION
var getBrowseActive = function (browserName) {
return navigator.userAgent.indexOf(browserName) > -1;
};
My best solution
function getBrowserInfo() {
const ua = navigator.userAgent; let tem;
let M = ua.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\s*(\d+)/i) || [];
if (/trident/i.test(M[1])) {
tem = /\brv[ :]+(\d+)/g.exec(ua) || [];
return { name: 'IE ', version: (tem[1] || '') };
}
if (M[1] === 'Chrome') {
tem = ua.match(/\bOPR\/(\d+)/);
if (tem != null) {
return { name: 'Opera', version: tem[1] };
}
}
M = M[2] ? [M[1], M[2]] : [navigator.appName, navigator.appVersion, '-?'];
tem = ua.match(/version\/(\d+)/i);
if (tem != null) {
M.splice(1, 1, tem[1]);
}
return {
name: M[0],
version: M[1],
};
}
getBrowserInfo();
