JavaScript - Determining The Javascript Engine Version In Ff
Some background might better help my actual problem. Feel free to address either with any relevant insights.
While attempting to create a greasemonkey script in FF2 (don't ask), I discovered that the "let" statement was causing my code to fail. After confirming that this statement has been available since FF2 (js engine 1.7) https://developer.mozilla.org/en/New_in_JavaScript_1.7, I became curious as one determines their javascript engine in FF. IE has a way to inspect the jscript engine, ala http://msdn.microsoft.com/en-us/libr...8VS.80%29.aspx , but I couldn't find anything similar for FF. Feel free to list links for testing engines in other browsers, too. I can't use irc at work, so it's good to know this place is still around for numb-nuts like me. :-) Many, many thanks (in-advance). Similar TutorialsHi everyone, I have a very simple question. I found some answers on the web but nothing quite concluding. I am hearing Search Engine can only be build with server-side programming or through google (which means your site must be connected to the internet. Is it possible to build a simple yet effective search engine for an in-house site (not connected to the net, only network) with JavaScript? My understanding is that, using arrays, once a user enter a word in a fied, the program would need to index all the pages containing the word. Then the program would need to target each seperate paragraph containing the word. Also what if the results must lead you to a document which must open in an iframe? Possible? How? Cheers Hello to all, I think that you will frequently read this boring sentence: "Javascript does not work with Firefox". Below a very very simple html with Javascript. Using MS IE v8 I have found that the code works very well. Filling nothings in the textfield "your name" and subsequently clicking on the button and a window will popup with the text "Sorry, you forget to: blah-blah ..." However, using Firefox instead...it does not work. A bit remarkable; the Javascript is very easy! Could you please check what went wrong? I have activated Javascript in the Firefox browser and the security is ok for Javascript. I hope that someone can provide me a useful hint.

For example, the following rules would apply: * must be a document element as the top-level parent element * must be at least one block element as a child of document * each block must have a unique key value * blocks can have 1...n p child elements. * p elements can have 0...n bold child elements What I'm looking for is an engine that executes on the client-side (JavaScript / jQuery) that can parse the XSD and flag any errors. In addition I would also need to be able to interrogate the engine in order to determine what are valid child nodes at a particular level of the XML. For example, the following types of queries might be asked of the engine: * Q: Is the overall XML valid? A: yes / no + report * Q: I'm looking at the element block (key="block2"). What are the valid child elements of this element? A: p (1...n). * Q: I'm looking at the element p in the first block (key="block1"). What are the valid child elements of this element? A: #text, bold (0...n). Determining the valid child elements of a particular element is something akin to how Visual Studio e.g. 2010 uses Intellisense. For example, given a schema Visual Studio let's you know what the valid elements are at a particular position as you type enter the XML. Finally I've mentioned XSD / XML above but we do not necessarily have to be constrained to these technologies so alternative ideas will be appreciated equally as well. Thank you for taking the time to examine my post. Can anyone get me a simple script for a search engine for my website? i cant find a decent 1 anywhere. thanks
Hey guys, While I know you cannot use javascript for SEO, I need something similar. What I need is something like a search and replace program or something that does this: it takes aspects of the filename and incorparates it into the meta tags. For example, if a file was named "1x9.html" I would want it to edit the meta tag Season 1 Episode 9 I was just wondering if you guys know if such a thing exists. Like I would write a script or something in the program, saying for it to search and replace meta tags in file names, and it would 1. Analyze the filename (for this example it will be "1x9.html" 2. Input " Season 1 Episode 9 " into the meta tags (analyzing the first character in "1x9" as [Season] [First Character] , analyzing the "x" in 1x9 as [Episode] and analyzing the last character in "1x9" as [Last Character] I need to do this for like 80 thousand files, and I cannot do it 1 by 1. All of the elements that need to be in the meta tags already exist in the webpage contents or webpage filename. I was wondering if you guys know the best way for me to go about this? Well, this is only beginning and kinda beta, but this is just awesome! This is 100% secured, but yet unfinished. This is huuuuuge! I've created temporal apache server on my computer to show how it works: http://80.222.127.106/downloads.php Hello, I have a question what is the best way to identify a browser, browser version and OS in javascript. I have try a few scripts but they all fail. This will help me out formating the code for diferent browsers. Thanks Hi All, I have HTML table with couple of columns with combobox in each row.when I select value in any of the combobox, I want to determine the column number of the combobox which is clicked.Is there any function which can be used to do this?Please help. Thanks, Anil Hello All, I am a JS newbie and I'm wondering if there a way to figure out the sentence from which a word has been highlighted. Essentially, when a user selects a word or a phrase, I should output the sentence from which it's been selected. Is this possible with JS or with any server side languages? - Pallav Code: closeElement.setAttribute('onClick', 'killElement()');
is not working in IE but works in mozilla browsers what is the appropriate IE version for the similar code? i've also tried: Code: closeElement.onclick = 'killElement()'; The latest version of MSIE fails to read the value of a popup menu in a form that I have. It worked fine in a previous version, and works in Firefox and Mac Safari. Here is an edited version of what I have: Code: var d = null;
function myTest(){
alert("mWunits value = ".concat(d.mWunits.value))
}
.
.
.
<body onload="d = document.forms[0];">
.
.
.
<form onsubmit="return false" >
<table align="center" border="0">
<tbody>
<tr>
<td align="right">Conductor Size (d):</td>
<td><input name="ef_dw" size="12"> </td>
<td align="left">
<select name="mWunits" size="1">
<option selected="selected">mm</option>
<option>AWG</option>
</select>
</td>
</tr>
.
.
.
The popup name is mWunits, and should have either "AWG" or "mm" as a value. And the function myTest() should display that value. However the value is an empty string. There is another popup in the same form, and it exhibits the same problem. My script reads the values of regular input fields just fine. As I said, this used to work under earlier MSIE versions, and works in other browsers. Has something been deprecated that I don't know about? Hi, i have a rating script which shows 5 stars and it allows users to vote out of 5 on certaiin things, the votes register ok but the stars dont change colour to show that the user has voted. this has happened since my host upgraded to php 5.3 and i noticed on IE(which i never use much) it says there is an error on the page and that error says Code: Webpage error details User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0) Timestamp: Tue, 2 Feb 2010 20:00:42 UTC Message: 'document.all[...]' is null or not an object Line: 96 Char: 9 Code: 0 URI: rating.js line 96 in the related file is Code: } else if(IE) {
document.all[div2show].innerHTML = text;
}
which only related to IE and not firefox so im unsure why my rating graphics do not show once selected. here is the entire js file is there anything in there that might be preventing it? Code: /*

many thanks for any help Luke i don't know what has changed in last releases of Firefox and Opera but before i used this script to detect browser versions (IE, Opera, FF) and block or redirect depending on version Code: <script language="javascript">
<!--
//Detect IE greater than 1 - we are blocking it completely
version=0
if (navigator.appVersion.indexOf("MSIE")!=-1){
temp=navigator.appVersion.split("MSIE")
version=parseFloat(temp[1])
}
if (version>1)
window.location="ie-error.html"
//Detect Opera less than 10 (9.80)
if (navigator.userAgent.indexOf("Opera")!=-1){
var versionindex=navigator.userAgent.indexOf("Opera")+6
if (parseInt(navigator.userAgent.charAt(versionindex))<9.8)
window.location="op-error.html"
else (window.location="index2.html")
}
//Detect Firefox less than 3.6
if (navigator.userAgent.indexOf("Firefox")!=-1){
var versionindex=navigator.userAgent.indexOf("Firefox")+8
if (parseInt(navigator.userAgent.charAt(versionindex))<3.6)
window.location="ff-error.html"
else (window.location="index2.html")
}
// -->
</script>
it worked last with Opera 9.5, FF 3.0 but after that it doesnt work at all Firefox'es version (3.6) doesn't get detected and is redirected to error page same goes with Opera (9.8 which is 10.0-10.5) can anyone tell me why this happens ? or can anyone "fix it" i know many people are against this kind of scripts (blockers and redirecters) but i do it so people who come with older and less compatible browsers with W3C standards to get warned so they don't load deformed page all, does anyone know if the setTimeout() function in js has been just recently supported? i created an online demonstration of a product that uses this function to delay the playing of .wav files after various second intervals. i know that Opera doesn't support this function because when I click my button, all of the .wav files that i have in the function that runs behind the button play at once. i have probably 10 wav files that are played throughout the function, at various conditional statements. does anyone know if earlier (like REALLY old) versions of IE do not support this function? or maybe ie8 doesn't support it? i developed this and tested it in all major browsers except IE8 and any version earlier than IE6. thank you for any help on this... Hi all, I'm currently working on a page that is presented to users which will check browser version, OS version etc. I've managed to do all of these checks with JavaScript but I'm struggling to find out how (or even IF) I can get what version of Windows Media Player the user has installed. We're looking to see if they have WMP11 or greater. The searching I've done has thrown up a couple of things (like a check to see if the version is 5.2 or 6.4 or higher by looking at mimeTypes). Basically can anyone confirm if this is actually possible and if so any pointers would be appreciated. Thanks in advance I am new to Javascript and I downloaded JSE internal search engine v 1.0a from CodingForums. It works fine in all browsers other than ie6 and ie7. Have confirmed that other javascripts are working in these browsers so it is not my browser settings. Can anyone help?
I'm trying to build a small chess like gaming engine, and i'm wondering what soulution would be better. To try and create the whole board in javascript, or to use flash instead! Problem is that is that i kinda don't have money to buy adobe/macromedia/flash but javascript could be a bit more difficult couse of browser limitations.. been searching everywhere for help on this javascript kit but no luck JSE internal seach engine v 1.0a http://www.javascriptkit.com/script/...se/index.shtml Description: JSE is a highly robust, 100% client side search engine for indexing and searching your own site, using JavaScript 1.3. Some of JSE's noteworthy features a * Uses regular expressions to efficiently and rapidly search the index for matches based on the entered keywords. Supports basic logic (ie: negation). * Returns the results on a seperate page from the search form itself, neatly formatted. Uses session cookies to transmit the query between the two pages. * Stores the index (url, keywords and description for each page you wish to be "crawled") in the "results" page. This means the index is loaded only when a search has actually been performed, saving on bandwidth and download time. * Searches title, description and desingated keywords within the index for a match. * Works in IE4+, NS4, and NS6+. its perfectly working on local server but when I uploaded my files to my webserver. it doesn't work. Is there anybody can help me with this? TIA Hey all, I have the old Yahoo! chess engine and Im making a webpage with a chessboard. Currently everything involved with this chessboard is wrapped up inside the code and dynamically creates everything it needs to operate. I have made a few customizations on several elements such as the PHP dropdown box that it dynamically creates as a quickjump to games. But i am wondering if someone wouldn't mind helping me in finding a way to write an amendment that reads 3 parts of the pgn file (Black)(Result)(White) (which it already does read them but just shows the info in the dropdown box) and display them as a header to the board. Everything in this script as far as variables go, are numbers... which makes it difficult at best which makes visual mapping harder. So I thought I would ask a professional what I should be looking for in the script so that I can go ahead and modify it and reuse some functionality to display a game header from javascript. The pgn viewer will read either string format directly input into the setup configuration in the html page, or it will read from a file. It them parses the elements based on the pgn tags. PHP Code: var tag=this.parseTag("FEN",pgn,i); if(tag&&tag!="?"){ this.board.startFen=tag; }else{ tag=this.parseTag("White",pgn,i); if(tag&&tag!="?"){ _68=tag; }else{ tag=this.parseTag("Black",pgn,i); if(tag&&tag!="?"){ _63=tag; }else{ tag=this.parseTag("Result",pgn,i); if(tag&&tag!="?"){ _62=tag; }else{ tag=this.parseTag("Event",pgn,i); if(tag&&tag!="?"){ _64=tag; }else{ tag=this.parseTag("Site",pgn,i); if(tag&&tag!="?"){ _65=tag; }else{ tag=this.parseTag("Date",pgn,i); if(tag&&tag!="?"){ _66=tag; So the variables I want to use are _68, _63, & _62 and display them as a header to the board. Any help is appreciated. |
