Cannot Set Property Of Null (error Only In Google Chrome)?
Jan 29, 2010
I am using a script called ajax_load.js that defines a function, ajaxpage(), that allows a person to load the contents of an external page into a div item. I have it setup so I may use ajaxpage() to load pages with other div items in it. The problem is that I cannot reference the div items loaded by ajaxpage(). I have provided an example below to illustrate this. It was working fine in the prior version of Google Chrome and is still working fine in IE 8, IE 7, and Firefox. The version of Chrome I am currently using is 4.0.249.78
Here is the example; All the files used in this example are listed below:
This code was working just fine in the prior stable version of chrome, and still works properly in IE 8, IE 7, and Firefox without any errors (The version of chrome giving me problems is 4.0.249.78). Does anyone know how to go about fixing this? Is this something wrong with the latest version of chrome, or is this on my end? The site I am currently working on relies heavily on this working, and having to change things means altering several thousand lines of code.
the error goes like this:Cannot read property 'events' of null.I would like to be able to provide more details, but I'm truly lost here, the calling function is this one:[code]This code is using the GeoExt Library plus open layers, but the error seems to be related to another reason non-related to the libraries.
This is turning up null all of a sudden. I'm running version 5.0.375.70
alert(document.styleSheets[0].cssRules);
shows null in chrome with a very simple test page and single css file with just one rule, but turns up as an CSSRuleList for FF Safari, Opera etc... document.styleSheets[0].rules is also null in my Chrome browser. How do i get the css rules in chrome? I think this actually used to work in my older versions of chrome but now I'm second guessing myself.
i have a top navigation bar with a clickable down arrow. once clicked a drop-down will appear. there are about 5 to 6 click downs. the content in the click downs are store in an external html file and i use an iframe to display it. so if 1 arrow is clicked content will show and if another is clicked while the 1st stays open, it should replace the 1st one. <snip/> I am getting an error that says TypeError: Cannot read property 'style' of null. the code line it's referring to is the one below with the stars:
I've been using this javascript (menu.js) for a drop down navigation menu for my site. Everything works well on it but in multiple browsers I get this error occurring on line 7 and 16 which is the d.className = "menuHover"; and d.className = "menuNormal";
Site - [URL] Location of js and css - [URL] The jCarousel works great in all other browsers, but in IE, when you get to the end of the jCarousel it gives the "Error: 'url' is null or not an object" pop up and it won't let me use the left arrow buttons to go back.
var book1 = bobj1.value; var chapter1 = cobj1.value; var verse1 = vobj1.value; var book2 = bobj2.value; var chapter2 = cobj2.value; var verse2 = vobj2.value; [Code].....
I don't know if this is written properly: if(bcv[a]!= ""){ The reason this is happening is because the error shows: Error: cobj1 is null Source File: [URL]
When I try and geocode an addres to my google map I receive the error: Object does not support this method or property I have gone over the script and can't work out what I did wrong.
I am doing a simple example of autocomplete textbox.Well whenever I am typing anything in the textbox it shows me the existing options as we know the default functionality of autocomplete textbox. Now I need that when I select one of the options from the autocomplete list droping below the textbox the blur function should execute so that the focus should get away from the textbox. I have tried document.getElementById('text1').blur() but it is not working in chrome and safari.
I've written a google maps app for work and have got it all running nicely...in chrome. I've only just noticed that for some reason it's not working in firefox or internet explorer. I was wondering if someone could take a look at the simple extract that I've made and show me where I'm going wrong (If I am):
Javascript: Code: function initialize() { if (GBrowserIsCompatible()) { //Create a div called map_canvas in the html where the map will be displayed var map = new GMap2(document.getElementById("map_canvas")); //Set the map to center on these coordinates map.setCenter(new GLatLng(55.872759,-4.297972), 15); [Code]..
i am working on a web project using jquery for many purposes like tooltip, action events on the page etc. So far I was using firefox as I had that browser only. today, i installed google chrome to see how the project looks in another browser. but I found a strange problem, all the java scripts which where working in firefox are not working now. i am unable to guess the reason, i have enabled javascrpt in the settings but still nothing seems to work.
Does anyone have a sizeable popup that will work in google chrome? I have tried several scripts for this with no success, they all open full page. Here is an example of what I am looking for. The problem with this is it opens a new page plus a full page popup
<script type="text/javascript"> <!-- function popup(url) { var is_chrome; var width = 1020; var height = 600; var left = (screen.width - width)/2; var top = (screen.height - height)/2; var params = 'width='+width+', height='+height; params += ', top='+top+', left='+left; params += ', directories=no'; params += ', location=no'; params += ', menubar=no'; params += ', resizable=yes'; params += ', scrollbars=yes'; params += ', status=no'; params += ', toolbar=no'; newwin=window.open(url,'windowname5', params); is_chrome= navigator.userAgent.toLowerCase().indexOf('chrome') > -1; if (is_chrome) {newwindow.parent.blur();} if (window.focus) {newwin.focus()} return false; } // --> </script>
To open I am using: onclick=popup(mypage.php?id=".$row->id."
I'm creating a custom text box.that's an easy thing to do for me but I encounter some problems on the javascript part.in the onfocus event of the textbox I try to get the caret position on the start.it works perfect on FF, IE and opera but I just can't get it to work in safari and google chrome. I found out both browsers use webkit but have no idea how you do it for the 2 browsers.I'm using asp.net ajax components for javascript and this works for the 3 browsers get_inputElement() = my textbox
I´ve just worte a few lines using $.ajax() to load an xml file and then parse it to create a carousel, the problem is that i've already probe it on chrome 3.1 and it was working perfectly, at this time chrome 5.0.x it doesn't work, it makes nothing, the success callback response is ok, but it doesn't load the reuqested elements , it's been proved on FF, Safari, IE, Opera
I tried the same code without apostrophes, but with no effect.
[Code]...
I found error... In POST variables passed to ajax.php I had 'content': content and content is probably jQuery reserved word (and this variable wasn´t define before). But I don´t know why that works in FF.
I am using a jQuery Slideshow on a website homepage that I am helping to develop.
The homepage can be seen here: [URL].. This site is currently in production and I am trying to make some improvements at the moment. But I cannot understand why the slideshow isn't behaving correctly in Chrome. I'll tell you what it is supposed to do.
1) Page loads... slideshow begins to loop through 4 slides, each linking to an article on the website.2) When you click on a thumbnail on the right of the slideshow, it should bring that slide into focus - You can then click on the "Read More" link in the description at the bottom of the main photo to go to that article.
Now here is what it is actually doing. 1) Page loads - slideshow begins to loop through the 4 slides, this is working.2) Click on a thumbnail and it does focus on that slide but it only brings up the image... the section containing the information/description and the link to the article is missing.3) The slideshow then continues to loop through the slides as usual but each time it comes to the slide you previously brought into focus, the information at the bottom is missing.
I have checked in other browsers and this does not appear to be happening. I have also checked in earlier versions of Chrome and this did not happen - It is only happening with the latest version of Chrome.
I have a website which includes stories with multiple chapters. These chapters have a set of clickable arrows at top and bottom to take you forwards and back through the chapters, including a "last chapter" arrow.When a story is in progress, the URL of the last chapter changes with each chapter added. Rather than having to go back into every previous chapter and change the URL of the last chapter by hand, I set them up so that the "last chapter" arrow is actually in an inline frame. That way, I only have to change the URL once, in the file go_end.htm which is the source for the frame. So both the picture of the arrow and its hyperlink are being accessed from outside.
My web pages are also set up to run on all major browsers and to detect the window width and resize all the artwork to fit, regardless of the browser and whether or not it accepts percentage sizes. Go_end.htm is no exception - it contains Javascript code which resizes the arrow so it is the same size as the ones which are actually in the parent page, outside the frame.This setup works perfectly in IE and Netscape, but Google Chrome either fails to display the arrow or makes it huge so it doesn't fit the frame. This seems to be because their superfast new Javascript editor is *too* fast. If I bung an alert command into go_end.htm, asking it to say the value of picWidth (the variable which sets the width of the arrow) as it loadfs, what happens is this.
Google Chrome displays an alert saying that picWidth is zero, then loads the first instance of the inline frame with no got-to-end arrow. Then it displays an alert giving a proper value for picWidth and loads the second inline frame with the arrow correctly displayed and sized. If I take out the alerts, it doesn't load the arrow in *either* frame. It's obvious that inserting the alert command somehow forces it to recognise the value of the variable which it then retains for long enough to load the arrow on the second pass.Any ideas for some command other than alert which would trick it into not loading the image until it's recognised the variable? If I put a time delay on loading the frame I can't see that that would help - the problem is that from the point at which it starts actually loading the frame it needs to wait for the variable to be set.
