Straight Html Or Dom Generated Html Objects Faster?
Jan 2, 2006
Im wondering if generating html objects such as tabels and rows in
javascript is faster than typing the html directly? Seems when you do
it in javascript you have to download alot of code and would slow down
displaying the page. while if you just type the html, it requires less
bandwidth and display faster?
is parsing html to display in browser slower than doing it through dom
to display the same html objects on the page?
I'd like to do something like this: After the page is loaded I have some forms with submit buttons. The buttons have a class called "open". By clicking any of these buttons the script is using AJAX to take some data from database and add some HTML to the document. This part of generated HTML has also buttons with a class "open". By clicking any of the new buttons script should do what it does with the old ones. The problem is I have no idea how to "refresh" a click function. After generating HTML it "sees" only the old buttons.
Here's some code:
$(document).ready(function(){ $(".open").click(function(){ var idVal = $(this).parent().parent().find("#PlaceId").val(); if($("#admin_places_"+idVal).html()=='')
How can I add an action to html generated by javascript?In the example below I add a link with the class 'example' to a div after a click on the 'test' link. (this is still working fine).Now, when I click the example link, nothing happens. How can I make this work?
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/ xhtml1-transitional.dtd"> <html lang="nl">
I was wondering if there was a way to view the html code that javascript produced since viewing the source code shows the javascript if statements for netcrape and IE etc.
This works fine - however, I'm also trying to call the same function via some HTML generated from a separate javascript file that performs validation, but can't figure out the code. I tried this to output to my errors array:
errors.push("<li>Please provide FULL details blah blah - <a href='#' class='link1'>click here</a></li><br />");
but clicking this just takes me back to the top of the page, rather than expanding the toggle.
JavaScript learner, first time poster. When I grow up, I want to be a JS guru. In the meantime, if I had hair, I'd have pulled it out yesterday. I've been working for a few days now, trying different techniques to perform what I think should be a simple function. Here's the situation:
I have an HTML page:[URL]... ...which calls a function in a JS file on another server [URL].. which I did not write, nor can I change. The JS file determines the date and time, checks it against a list of conditions, then displays one of two gifs indicating whether or not an online help person is expected to be online, based on the date and time.
The list of conditions in the JS changes from time to time (holidays), so I want to continue calling the JS but the problem is the graphic it references does not fit into our available space for it. The function within the JS:
I'm trying to add dynamically generated HTML after the page has loaded. I've tried two versions.The latest versions is this, using insertBefore (as appendChild is buggy in a few browsers according to the SitePoint reference) ...
Code:
addImageField: function(x) { var newNode = createImageField(x); var src = document.getElementById("imageUploads");
[code]...
The first alert returns: object HTMLFieldsetElement .The second alert returns: object HTMLDivElement....and the third alert fails to fire, indicating a problem with the code above.Note that if I change the problem line to remove the null reference it still doesn't work (again the third alert won't fire):
I have a script (more of a web app) which generates a customized table element. I want the user to be able to "save" this table. Thus far, what I am doing is getting the HTML of the table and displaying in a textarea for the user to cut and paste to a text editor. This is fine, except, I worry many in my target audience wont know how to use a text editor, or make plain text, or save as HTML.. etc. So I was hoping to use .js to open a new window and write in the HTML so that the users could merely do a FILE>SAVE PAGE AS directly from their browsers.
I suppose I have two questions: 1) How do I document.write to a NEW window?? 2) I have noticed that when you use.js to generate HTML, it doesn't show in the view source , thus it wont "save as" anything else but a BLANK doc. How to make generated HTML "visible" so that it can be saved.
why does this not work for clickable images -essentially buttons, generated by ajax response but works if you just put it all on one page the image (works when pre generated, but not when generated by an ajax response):
<img src='img/minus-8.png' class='button' /> the javascript: $(document).ready(function(){
I was wondering if there was an easy way to dump the html that gets generated after the page gets loaded to verify it's what I wanted and expected (I'd like to check out the source, not just the results).
I've seen lots of examples of invoking the getElementById and they always are given as a method of the document object. That is, they always show something like: Code: var theElement = document.getElementById("Fred"); But what I'd really like to do is to get an element from the document, but starting at a particular element in the hierarchy of the document.
For example, suppose I have two forms, form1 and form2, and they both have elements in them named "Fred" (and, yes, I know I shouldn't do that). But what I'd really like to do is something like: Code: var theElement = form1Element.getElementById("Fred"); assuming that I've already somehow retrieved the form1Element.
But Javascript reports to me that getElementById is not a method of form1Element. And the fact that every example I've ever seen of getElementById invokes it as a method of document would seem to bear that out. The thing is, on the microsoft site it actually shows the generic form of the method as: Code: object.getElementById(iD)
Which would seem to imply that it's more generic than just being a strictly document method, that perhaps it's intended to be a method of at least some additional HTML objects. Since that doesn't seem to be the case, how might I go about doing what I'd like to d, which is find the occurrence of the element, by its ID, but only within a particular section of the document hierarchy?
I am ok with using objects creating classes if someone else defines, but when it comes to defining my own, I hit a nasty brick wall... I am using an XML/XSLT wrapper called Sarissa to help with programming a utility to transform XML into HTML in different views. For this to happen, I have created a Loader class which loads in XML required. I am aware of prototyping for binding methods to objects (as opposed to replicating the same method every time an instance is created)... The aim being I want to create a progress bar for the essential files that need to be loaded in. Presently I have them load in Synchronous mode just to get the utility working, which I know is poor, so would like to address it.
I'm trying to figure out if there's an easy way to execute all the Javascript code included or referenced in an HTML document even if given code references DOM objects.I basically have some Javascript code that makes a POST to my server. The POST payload includes a unique identifier for that html page, so I know if the JS was successfully executed if I see the unique identifier in my server's logs.
At first I wanted to test if the javascript in 5 pages worked, so I manually opened the 5 sites and verified my logs. I then wanted to see if the JS in 100 pages worked, so I wrote a little script that launches 100 tabs in FF staggered (I also used a nifty tool -- autocomplete, to close old tabs). I then wrote a utility to go through my server's logs and verify that the 100 unique identifiers that I was expecting were there... So this also worked fine!But now I want to move forward and test 1K or maybe even 10K sites. Is there anything I can use to execute Javascript embedded in an html page? Hopefully asynchronously?
I need suggestion for this.After a particular option selection in my page,how to replace the rest of the contents of the same page with its response,and too making the select action invisible... can i do it using ajax wit html. for example,i have a select option,where for each option is attached a new set of objects,i want them to be loaded on the same page at run time,without page refresh...
I'm building a webpage using javascript and iframes. Basically I have an iframe in the middle of the index.html page that links to another html page (let's call it iframe.html). My question is, is it possible to call a javascript function from iframe.html to control an object on index.html? If so, how do I do this? I'd like to be able to assign an image in iframe.html with the hyperlink of href="javascript:function()", where the function effects the CSS of a div on index.html.
I have a web site which main page is index2.html I need a script that when I refresh the page it takes me to index3.html or index#.html in a random fashion. the list of index numbers is 10 so far.
I came across a very odd browser behavior when trying to modify a css class using javascript and at the same time having a base html statement in my html file.Without the base html statement, all browsers work fine and I can change the css class definition using javascript easily.With a base html statement, only FireFox still works while Internet Explorer and Google Chrome dont work anymore. If there is a cross-domain issue, while one browser does work and the others dont? An example of what I'm talking about, with the base statement:
http://freebsdcluster.org/~casaschi/tmp/example-base.html Without the base statement: http://freebsdcluster.org/~casaschi/tmp/example-nobase.html
how to tweak the code in the case with the base html statement in order for the javascript to work with all browser (modifying the class definition) ?I want to be able to manipulare css classes with javascript when a base html statement is in my html code.This is essentially the code:
When I test alert() the .html() contents it appears like this. It seems to screw up the quote escape and changes " to " ;="" after the recordchecks().[code]...
So even though the source code looks perfect, if I alert() the div contents with html() it seems to get a bit garbled in the process.
I tried to load 1 html through ajax and javascript and it worked.But i want to load more than one and i cant.I thought that it would be a good idea to put the ajax files to the external websites and put the same load button.I tried this idea but it doesn work.I can only load one external website.
I have a file that generates web galleries in Adobe Lightroom. They are generated depending on which files are selected and the metadata in those files.
Basically it is a series of pages of thumbnails called index.html index_1.html index_2.html etc.
Then a set of pages for each individual image.
An example can be seen here: [url](the page navigation links are not great, but I have addressed that, they're at the bottom >> )
Currently if a user clicks on a photo there is a 'return to thumbnails button at the top, but this always takes them to /index.html
So the user could be at a picture after browsing to /index_39.html and still get returned to /index
Is there any way I can use history.go to find the last instance of index.html Or index_x.html (where x is any number) and take them back to that instead?
