Dynamically Generated Table With Alternating Row Colors?
Aug 4, 2009
I'm using a javascript to alternate table rows and it works fine by table id, and on the first loop. This is all inside a conditional, in which the table tag is repeated.
On the second and subsequent loops, the alternating row color fails because there can only be one unique id call to a page. Right?
What's the script that will allow unlimited reiterations of tables with alternating row colors, using class?
I read this article: [URL]...I want to Combine this example with the example given in Part 1 to give this table of revenues alternating row colors!
Here are my combining codes: It is quite clear there must be something with them because I can't see the expected result after running. Help me find that mistake.
Out of pure curiosity: Assuming tabulated data in HTML is being generated by a PHP script, would it be better to alternate each row's background color with PHP or rely on JS to do it? One is run client-side and the other server-side so my guess you have to take the whole web app as a whole and see which side should be spared the additional workload. Is it situational or is there an absolute rule? In a vacuum, I guess you could argue PHP would be better since it cannot be turned off in the way JS can (unless plugins like NoScript can block PHP as well), but I don't have enough experience with either to be sure.
At this point I have been able to add the row. But what I want to do and am having trouble with is alternating the row colour to the dynamically added row element.
Sample of code I am using:
Code: var tbody = document.getElementById('tableItems');
var td1 = document.createElement("td"); td1.appendChild(document.createTextNode(qty)); td1.setAttribute("class","qty"); row.appendChild(td1); tbody.appendChild(row); One thing that puzzles me, is that even after adding a row the table my table.rows.length still = 0.
Does anyone know how I can determine the appropriate amount of rows so that I can apply the appropriate class?
Or is there just something blatantly wrong in my approach?
Alright so for a school assignment I need to create a button with the name of the color it is going to turn the background to. the assignment says nothing about naming the buttons the hex numbers for the color therefore: I was curious if someone could show me how to create a button in java script that would generate a random hex number for a color ie: #+()+()+()+()+()+() and the text shown on the button would be the same as the hex number generated.
I have DIV section with a CSS class that defines a gradient. However, when the user clicks a button, I want to dynamically change the two colors of gradient via Javascript. What is the DOM structure to change the colors in this field similar to this command: document.getElementById('content1').style.color = p_color;
I have a master table list containing 30 songs and a "play" button at the bottom of the page.when i click on "play" button it should generate one more table containing 5 random songs from the master table above. each of these rows should be loaded dyanamically after the previous song is played. As the song random song is played in the second list that same song should be highlighted in the first list dynamically. How can i do this using javascript. I have the first part of generating the list of 30 songs.How can i continue from there.
I need to make the backgrounds on certain rows a different color to get the info to read better. I used the following: <!-- Directory of Staff Row Backgrounds --> <script type="text/javascript"> $(document).ready(function() { $('tr:odd').addClass('odd'); }); </script> But instead of starting over with a new table it seems to just have counted them all so it looks off. Here is the page: [URL].
I want to have <div> cells that the background-color css style dynamically change between 4 colors depending on how many times they are clicked. The options are none, yellow, red and green then repeat. So when the page loads, they are all at none, and if you click once it goes to green, twice to yellow, three times to red, then back to none.
Any way to change row colors of table based on content.
For example: <span style="font-family: courier new,monospace;">+-----|-----------------------+</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">|acess| COSTUMER |</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">|-----------------------------|</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">| 1 | joseph |</span> <span style="font-family: courier new,monospace;">| 2 | mary | </span><span style="font-family: courier new,monospace;">| 3 | john | </span><span style="font-family: courier new,monospace;">| 4 | joseph | </span><span style="font-family: courier new,monospace;">| 5 | joseph | </span><span style="font-family: courier new,monospace;">| 6 | guile | </span><span style="font-family: courier new,monospace;">| 7 | mary | </span><span style="font-family: courier new,monospace;">| 8 | craig | +-----------------------------+<br style="font-family: courier new,monospace;"> </span><span style="font-family: courier new,monospace;"></span> in this table, the name Joseph and Mary are repeated, so, every "joseph" or "mary" row must have the same color (picked randomly or not). so as every "craig", "guile" or "john" row.
I don't want to use css class names based on the name of the "costumers" because I don't know how many costumers are and how many times they appear or repeat.
I have this table with alternate row colors. Class gray and class white. I have javascript that do highlight when mouseover row ... and onclick to select row and highlight it with another color. Also created a class called "Selected". You can only select a row at a time.
My problem is, if a row is preselected, when mouseover the selected row, the selected color is screwed. Until you click on the selected row once, the behaviour is correct again. Code:
I want to dynamically generate list box options using the content of an sql database in real time. More specifically, i have a page with a couple of listboxes, when i click on an option in the first list box, i want the second list box to update with options that reflect the first one, in real time generated by the sql database.now i was wondering if it might be possible for javascript to send some thing to php which php could decode and search the database and return the results of that search. here is how i imagine the process to look in psudeo code:- user clicks on an option (say the 3rd option) in the 1st listbox- javascript catches the event, and sends some data to php indicating the 3rd option from the 1st listbox has been clicked- php tells sql to search for records that correlate with the 3rd option from listbox 1- php sends search result back to javascript- javascript populates the 2nd listbox with search resultsi want to do this with out having to refresh the webpage, security issues aint high, cause this project probably aint gonna go on the web. I got the idea from the dynamic searching on google, so i guess such technology is possible some how.
I'm stumped on a jQuery related development task. I'm using jQuery in a SharePoint Web Part...The web part pulls data from a list and displays each item as a link button. When the link button is clicked it uses the jQuery-UI to display the body of the list item in a dialog box. I have this working perfectly when all of the class names are hardcoded. So in this code dialog0 is the class name for the body of the first article. newTitle0 is the linkbutton so they correspond 1:1 (and so on Dialog1, newsTitle1 etc..)
Problem is, when I have more than 1 instance of the web part on a page, because they use the same class names (2nd web part would also use Dialog0, newTitle0), if I click on an item in one web part, the item with the same class name opens in the other web part as well.
I've implemented it so each item now has a unique ID but I don't know where to go from here, so multiple instances of the web part can be on the page, and have the jQuery know which body to display when a link is clicked.
I'm having a problem with the page at http://www.bathfringe.co.uk/contributors2011_2.php The user is able to add new performances to the form. This functionality is provided by cloning elementsPart of the code should add a 'counter' array key to the names of the cloned form inputs (full code obviously available at the page linked above):
function selectDefaults(buttonGroup){ for (i=0; i < buttonGroup.length; i++) {
if (buttonGroup[i].checked == true) { for (count=1;count < document.addForm.recordCount.value; count++) { var doc = document.addForm.feature1[i] var featureVal = doc.value; featureVal = featureVal.substring(0,2); if ( featureVal == "SF"){ doc.checked = true} } }}}
I need help in the second 'for' loop. Currently it is hard coded to replace the value of document.addForm.feature1 - but this field name is dynamically generated via the page it resides within. That being said, its name/id will increment depending on how large the recordset is. i.e. feature2, feature3, feature4 etc....
How do I get this to work in the javascript? I need to use this script to search all the 'feature#' fields in the form when the script is triggered. All I could think of was this: var doc = document.addForm.feature+count+[i] which gives me a syntax error.
The purpose of this script, for those who will wish to know, is to automatically select all the features of the product that have the text "SF" (standard feature) in their value.
I cant seem to get the reference to the 'header' IFrame that is dynamically created. I can reference one called 'footer' that is created in the same line of code as the other IFrames however (oddly enough). I've tried numerous ways with no luck. Since this is inherited code and designed years ago to run on IE only it's a mess. You'll see I've tried alerting out various different ways and simply left it in to show my feabile attempts.
Code: function mit(e) { var iframeElement = document.getElementById('header');
And I doing some validation like this. function checkvalue() { var f = document.forms['formA']; var eLen = f.elements.length; for (var i=0; i<eLen; i++) { if(f.elements[i].name == "text_" + i) { alert ( f.elements[i].name); } else { alert (f.elements[i].name); } }
It never goes into first part of if statement.. Is there a way I can access these kind form elements..
I have a jsp file that is used to display data from Java objects running on my server. I'm using JQuery for tabs and to handle the ajax calls to a servlet that affects the Java server I have running.Each tab represents a service, and has a corresponding java object on the server side. These are generated from the spring configuration, and is working fine. The page is used to control some aspects of the service, and I have a few buttons that can be clicked. I'm trying to get it so that when a button is pressed, the appropriate Java function is called on the service's object (this happens using ajax) and then refresh the current tab.
My js code is like this:
function doPause(params) { //some additional params set doAjax(params);
[code]....
Right now, I'm using the window.location.reload(true) to refresh the whole page but I'd like to just redo the div for the tab that contains the button that has been clicked.I have tried:
There can be any number of 'groups' but I would want to apply some validation for each item in a group. I can only see that the validation is done by specifying a id? however as the id's are going to be dynamically created how can I do this? can you validate for a css class?
The id tag links to a js script on a remote server and replaces the "loading" text with the song title of the currently playing song on my shoutcast server, and refreshes this every 60 seconds. I want to be able to grab this song title and put it in a php variable. I don't have access to the remote server, so I don't have any other way of getting the updated song title outside of this little snippet. I tried using php output buffering but all that does is grab the html I posted above, and not the javascript-generated song title.
I want to add an event to a generated SELECT field. It's an onChange call to a function named calculateSubtotal(). The result I want would look like <select name="..." id="..." onChange="calculateSubtotal()">.
This is what I've got so far. The drop menu is created with no error, but no onChange either. Code:
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):
