.html() Garbles Div Information - If I Alert() The Div Contents With Html() It Seems To Get A Bit Garbled In The Process?
Dec 28, 2010
It appears that .html() is somehow messing up reading the contents of a div.Here is my php code which loads into the div.
$own_pre_selection .= "<input name='" . mysql_result($result,$i,"did") . "' value='" . mysql_result($result,$i,"did") . "' type='hidden'><span class='addremove' onclick="recordchecks('" . mysql_result($result,$i,"dname") . "','" . mysql_result($result,$i,"did") . "')";><u>Remove</u></span> " . mysql_result($result,$i,"dname") . "<br>";
Here is what I see as source code after the page renders.
<input name='677' value='677' type='hidden'><span class='addremove' onclick="recordchecks('Heart Neoplasms','677')";><u>Remove</u></span> Heart Neoplasms<br><input name='1298' value='1298' type='hidden'><span class='addremove' onclick="recordchecks('Heart Septal Defects; Atrial','1298')";><u>Remove</u></span> Heart Septal Defects; Atrial<br></div>
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.

So, I doing this bit of code for a pagination, but havingproblemswith my next, and back buttons.So I cam up with the idea to store the current page number in between two <p> tags. So the say the current page is 5, it would be shown in html as <p>5</p>My question is, with using jquery, can i get the 5 from the two p's, ive manage to stick the 5 into the two <p>'s using jquery, the code:$("#current").html(pageNum);with #current being the <p> id and pageNum being the 5.i have triedvar prevNum = $("#current").get(0);for getting the number but didnt work also here the jquery code, incase you want a full scope of what going on
<script type="text/javascript">
$(document).ready(function(){
//Display Loading Image
[code]....

This question may appear opposite of most, but I'm learning JS using a book and I can't understand why/how this particular code works. I'm working on simply retrieving and passing information to and from html forms. This is a very simple script that will change what is selected in the drop down box depending on a button push.
Here is the script:
Code:
function flip(pizzatype) {
if (pizzatype.value == "Veggie Special") {
document.forms["pizzaform"].topping.value = "veggies";
} else if (pizzatype.value == "Meat Special") {
document.forms["pizzaform"].topping.value = "meat";
} else if (pizzatype.value == "Hawaiian") {
document.forms["pizzaform"].topping.value = "hampineapple";
}}
And here is the form's html:
Code:
<form id="pizzaform" action="#" onsubmit="return false;">
<p>
<input type="button" name="veggiespecial" onclick="flip(veggiespecial)"
value="Veggie Special"/>
<input type="button" onclick="flip(meatspecial)" name="meatspecial"
value="Meat Special" />
<input type="button" onclick="flip(hawaiian)" name="hawaiian"
value="Hawaiian" />
</p>
<p>Main Topping: <select name="topping">
<option value="cheese" selected="selected">Cheese</option>
<option value="veggies">Veggies</option>
<option value="meat">Meat</option>
<option value="hampineapple">Ham & Pineapples</option>
</select></p>
</form>
The way I see it is the button onclick will call the flip function and pass it a var, for example "veggiespecial". I understand the code that will perform the actual change on the drop down menu. What I don't understand is the if statement.
if(pizzatype.value == "veggiespecial")...
Shouldn't it be just (pizzatype == "veggiespecial")?
Why does it have to be pizzatype.value? Where the heck does the .value come from???

I can't seem to extract XML from an somepage.xml document and display it on a regular webpage. I have no way of reading its contents.
I read up on some microsoft way of doing it, but not sure that is gonna fly (need it for most browsers), so can this be done easily with json/ajax?
I have an xml file in normal format:
www.somedomain.com/somepath/somexml.xml
<products>
<items>
<item>blah</item>
[Code]....
So, how do I get that data to manipulate and display in my html? I don't even know where to begin with json/ajx etc.. and how to call the xml file etc..

How can I use Javascript to access an external website (a href...) and capture the contents of a particular HTML tag. I thought ".innnerHTML" might do it but I've tried several configurations and can't seem to figure out how. I'm not even sure that it's possible.

There is a project called Seed which allows JavaScript programs to run on the Linux desktop. There is connected project called SeedKit which runs HTML files as a Graphical User Interface front end for JavaScript files run by Seed. It acts like a webpage which rather than linked to a web-server is linked to a JavaScript program with HTML events like buton clicks etc that drives JavaScript much in the same way as normal desktop Graphical toolkits do. I hope this page from my blog starts a bit.
http:[url]....
Both projects are quite new so is very experimental. I am not involved in the development of any of the projects but I am trying to create a few examples to show how it works. My first example is to take the contents of the log folder /var/log, display it in the SeedKit HTML file and when a user clicks on it, it displays the contents of the log file.The way I am going about this is firstly to create a two column table in the HTML thus:
<!DOCTYPE html>
<html lang="en">
<head>[code]....
The table on the HTML file is populated with the file names but I can't get the contents of the specific div I have clicked on. I tried $(this).text() but it displays all the text in the table.

How do you update the contents of a form from a click of a button? I can poplate the contents of a table that is inside a form on the initial creation of the page
<form id="form1" name="form1" method="post" action="">
<p align="center">
List of Dying Patients
</p> <br><br>
<table border="1" align="center">
<tr>
<td>Last Name</td>
<td>First Name</td>
<td>Middle Initial</td>
<td>Date of Birth</td>
<td>SS Number</td>
<td>Marital Status</td>
<td>Gender</td>
</tr>
<script>
populatePatientsList();
</script>
</table>
</form>
and this is the contents of the function populatePatientList();
for (var x=0;x<mainArr.length;x++) {
document.write("<tr>" +
"<td>" + mainArr[x][0] + "</td>" +
"<td>" + mainArr[x][1] + "</td>" +
"<td>" + mainArr[x][2] + "</td>" +
"<td>" + mainArr[x][3] + "</td>" +
"<td>" + mainArr[x][4] + "</td>" +
"<td>" + mainArr[x][5] + "</td>" +
"<td>" + mainArr[x][6] + "</td>" +
"</tr>");
}
After this the table will have all the contents of the array. How do I reinvoke the form to have the updated version of the array shown on the table without refreshing the whole page? The page cannot be refreshed because the data is just in an array and when I do refresh the page the contents of the array gets back to its default. Is it even possible to refresh just a part of a page, in my case a table after a button click or are there other button events I can try to play with?

I have a web site where multiple html pages are opened at a time & messages are received or those pages are refreshed automatically using meta-tag.
what I want is whenever that page is refreshed, the particular html window should notify user (as user may have opened other html window), now notification could be by setting focus to that html window which is refreshed, but then this will distract & frustate the user as he was referring other html window. What I would like to do is make that window blink or some notification like yahoo or msn mail received. But I want this kind of feature in HTML/Javascript.

I have this script that will read all the headers (h1-h6) in your HTML document and also HTML comment tags which are specially recognized, and it will create an HTML document "table of contents" (or outline) and insert it as a DIV within the document. This is for people with ESPECIALLY LONG HTML documents...it makes sense for this purpose.
The script is attached to this post in a zip. The zip archive has four JS files. 'htmlTOCgenerator.js' has all the meat of getting the nodes and generating the DOM nodes for the ToC. The other three have 'support' functions and are included. The 'colorContrasting.js' file is actually supposed to compute 'complementary' colors from random color generation. Why? Refresh the document each time, and the ToC has a different foreground (text) and background color, that's why. Breaks up the monotony. A large comment block inside 'htmlTOCgenerator.js' tells the document maker how to set up the HTML document for making this work.
In a first version, this script inserted the ToC ('table of contents') at the top of the document where the HTML comment tag "<!-- putTOChere -->" was placed/found.
Then I decided it was better to place the ToC DIV element to the left of the text, in a fixed block (does not scroll with text). The ToC DIV contents themselves are scrollable in case the contents would go beneath the bottom of the client window height--can't have that.
Click here to see an example of how it works:
I am having problems with it though.
1. The scrollbar on the ToC block always shows, even if the contents don't fill up the block. The CSS is set for 'overflow-y:scroll' but that does not mean the scrollbar does not show if there is no overflow. It would be nice to control that. Still have not figured it out.
For an example of not enough headers to fill out the height-specified (by necessity) fixed DIV block, see this page.
2. In my documents, the main body of text is all wrapped in a DIV with its right- and left-margins set to 'auto', so that when user widens or narrows the client window, the text is always centered. I need to stop the main body text from running behind the TOC during a narrowing of the client window. I thought setting the right margin of the ToC DIV should stop that. Anyway, that is a CSS styling problem, I suppose, although the CSS must be set through script (I do through script since the instructions don't require the document maker to set up CSS: too many instructions become annoying for anyone wanting utility in the script). And if you think frames are answer, that complicates matters and I believe it gets away from the eventuality when frames are deprecated.
3. I also want criticism on how to make this presentation/structuring/interaction of the ToC block better or workable.

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 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:
<!--
-->
<base href='http://www.google.com'>
<style id='myStyle' type='text/css'>[code]....

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?
