How can I modify a page before it is rendered? I tried using greasemonkey to remove a script, but it runs it anyway. Is there some way I can get rid of a script on a page before it runs.
What I originally tried to do was removeChild, but that of course is done after the page is rendered. Then I tried wrapping the script in <noscript> tags, and it still was executed.
If the user clicks a link in my webpage then a text gets updated. However, one text is too long and I need to put a HTML line-break into it. When I stick in a <brthe <brwill simply appear in the web page. I have no idea how to make the browser interpret the <br>.
I know there is a workaround solution by putting the text in a invisible table cell. However, then I cannot set where the lines break......
I have been working with the cluetip plug-in for several hours and am stuck. I can get most of the functionality working, but am unable to load another page within the tip and see the formatted html. The text shows up in the tip without formatting. The CSS for the tooltip itself is working as expected. I have tried copying and pasting the html from the fragment pages on the cluetip demo site, but am having the same issue. I am using the exact code used in the 2nd example on the demo page: [url]
refer to my development site - [URL]... If viewed in IE6, it has no header graphic and no border graphics. Before the implimentation of PNGFIX it looked like attachment image 1. After implimentation it looks like attachment image 2 The files in use are jquery-1.3.2.min.js and jquery.pngFix.js. I have also tried using jquery-1.4.4.min.js but this does not change the situation. jquery-1.3.2.min.js has been reverted to as it is native to the Coppermine Gallery.
I want to write a select control and use a Javascript function to handle all click events on the control. Under certain circumstances I also wish to prevent the dropdown's list from being rendered.
Here is a sample showing what I am _unsuccessfully_ trying to do.
i came up zero when trying to find a direct method/value in the javascript object of the Node to determine wether an object is shown or not. So i wrote the following function. it checks relative to a parent (which could by document.body or a form or something) if somewhere on the way to that parental fixpoint a display='none' is found. If theres a better/faster or even direct way to do this please let me know, otherwise enjoy this function.
P.S. i did not optimize it for IE since it doesn't support the prototype anyway
Node.prototype.visibleByInherit=function(s) { var p=this; var v=true; do { if(p.style!=null) if(p.style.display!=null) if(p.style.display.toLowerCase()=='none') v=false; p=p.parentNode; } while(p!=null && p.parentNode!=null && p!=s.parentNode && v); return v; }
I have some initialization to be done at page load time, which changes the text of some anchors so that they are consistent with the query string (these anchors are used as criteria selectors, and should be initialized to the criteria contained within the url).
IE and Safari fire the onload event before rendering any elements, so when the event handler synchronizes the anchors, they are rendered with the right contents immediately. Firefox, though, renders the page first, and then fires the handler, which results in the anchors getting their initial values, and then changing to proper selections. I've tried calling my init() method immediately after the anchors are defined in my document - no difference, looks like Firefox is rendering everything as soon as it's encountered in the document.
Is there any way to have my code run before any elements are rendered in Firefox? Currently I've "solved" this by hiding the containing div in the document, and showing it after making changes. This results in the UI visually reloading itself with each new page, which is not very desirable either.
I have an issue where I am trying to allow the user to click on a table and automatically copy a table into the clipboard. I do this with text using IE:
function clickCopyText(fi) { window.clipboardData.setData("Text",fi.innerText); }
so to copy the table, I tried:
function clickCopyHTML(fi) { window.clipboardData.setData("Text",fi.innerHTML); }
The Trouble with Tables is the HTML itself gets copied as opposed to the rendered table. I am probably looking at some other way of getting the code to the clipboard, but I am stymied. I can do it with images, but not with rendered HTML.
suppose we have a <a href=www.google.com>google</a> tag in our HTML page.And it is inside a div with class name as chapter. Now i added the script as below,
I am trying reload a div on a page with content from another page using ajax.I am able to do this but the problem is that I need to wait for the page (that I am sending an ajax request to) to finish inputing all the relevant html before it is shown on the page calling the ajax otherwise the re-load of the div will not be up-to-date.
I am having a problem accessing and element by ID in a script that runs via 'window.onload' at the end of all my script definitions. Do the HTML elements exist at that point or should I look somewhere else for a bug?
How you handle back button scenario in firefox browser. The problem is when i click browser back button , the javascript on load is not executed and page is rendered from cache.
I have a page with 2 drop-down menus. The task is, when you select 1 menu, your selection then changes the options available in the other. This data happens to be drawn from a mysql database, so I wouldn't think that it could be done purely in Javascript, but rather a combination of PHP generating some JS code. Thing is, I don't even see how to change a menu's available options with JavaScript, only names and values of individual fields.
The basic concept is a music playlist that I'm trying to write as a table inside a div.
I have Song and Playlist 'classes'. The Song class has a Write() method, as does the Playlist.
The Song.Write() boils down to this: var tr = document.createElement("TR"); var td = document.createElement("TD"); tr.id = this.ID; tr.appendChild(td); td.innerText = this.Artist + ' - ' + this.Title; td.onclick = function() {top.playSong(this.parentElement.id);} return tr;
The Playlist.Write() call is essentially this: // this.songs is an Array of Song objects for (var x = 0; x < this.songs.length; x++) { playlistTable.appendChild(this.songs[x].Write()); }
When I attempt to call playlistTable.appendChild() after creating the table via document.createElement("Table"), everything works fine, except I have no way to add the table to my document, since the div I want it in won't believe that appendChild() is a valid method. If I put the table in the div as a <TABLE>, and then try to append to that, the *table* doesn't accept appendChild() as valid. Specifically, I get an 'Invalid argument' error when calling either.
I have been working on an autocomplete script that I have modified to be used with JSP's/Servlets. The script is working very nicely, except for one minor issue. When the user selects from the suggestions in the drop down list, for some unexplained reason, an extra space is added to the word in the text field. Also, I would like to modify this script further, such that if a user enters more than one word in the text field, the autocomplete script is activated for each word, instead of ONLY the first word.
I have added the entire code for the JavaScript file that is responsible for the autocomplete feature below.
The link from where you can download the autocomplete files is here:
[URL]
a demo of the script can be found here:
[URL]
FYI, I am using the version that uses XML.
Below is the JavaScript code for the autocomplete file I am using:
if(typeof(bsn)=="undefined")_b=bsn={};if(typeof(_b.Autosuggest)=="undefined")_b.Autosuggest={};else alert("Autosuggest is already set!");_b.AutoSuggest=function(b,c){if(!document.getElementById)return 0;this.fld=_b.DOM.gE(b);if(!this.fld)return
First though JS is not my strong suit and the above code is something I found at the W3School site or whatever it is. What I would like to do if possible is add a Cancel button to the alert box that when clicked cancels the form submission it's attached to and keeps the user on the current page to modify the data they entered in to the form should they want to change it. As it stands, all there is is an Ok button and if you click the red x in the corner it acts as if you clicked ok so if a user wanted to change their form data they'd have to close the browser to start again. Aside from liking to add a cancel button I would also like to if possible change the alerts Ok button to read something different. Not sure yet, thinking either Submit or Proceed.
I’m trying to modify a DHTML editor that parses a style-sheet via PHP and instead of modifying the tags via execCommand(), find a way of writing inline styles by way of adding <span style=> tags around the selected text.
Easier said than done. My first though was to do a search and replace on the innerHTML, but falls down if there is more than one match (it will only modify the first occurrence). I suspect that even if I could find the text around the selected area, this could still fall down for same reason.
So, I’ve got the selected text via the createTextRange() method. How do I modify this text and write it back out to the textarea.
I have a form which houses basic inputs, as well as a few multiple select forms.
I need to parse all the 'values' which are in this multiple select form (it gets manipulated dynamically client side). I wanted to create a function that loops through all the form elements, and if the type 'select-multiple' is detected, gather the VALUES of each <option> inside it.
The bit I'm stuck on is then how to reconstruct this into a form submission. Preferably I wanted the data from the 'select-multiple' element to be submitted as comma delimited, eg 14,12,512,63,62 which would later be parsed by PHP.
I was considering reconstructing a query string and submitting that as GET, but I'd prefer to POST it along with the other data (such as INPUTS etc) which do not need to be changed.
Can I somehow attach some 'hidden' type data onto the end of the form submission at this point?
