Locating Specific INPUT Tag Within A TD Tag With No Id And No Name?

Nov 10, 2009

We have a commercial shopping cart software installed on our website and since it is proprietary, we do not have access to source code. But they do allow you to include custom javascript on the web pages that they generate. What I want to do is add some text after a specifc INPUT tag that appears on the page within a TD tag. The problem is, that they do not have any specifc ID assigned to the INPUT or TD tag, and although the INPUT tag has a name assigned to it, the name is used in other tags as well and is not unique.

Below is the code that I used to solve the problem, but I want to know if there is a more efficient way to do it... Basically my code grabs every TD tag on the page, and then loops thru all of them looking for the specifc INPUT tag characteristics and then inserts the text afterwards (it needs to work in both Firefox and IE so you cannot use innerHTML).

Locating Searching For Text Within Iframe Or Frame?

Aug 18, 2010

[URL]

I would like to utilize this script where I could pass the string of words to another page.

Meaning, search for the text, actually a word, then take the two words following the searched text and have them passed to the next page...I have tried to "alert" the words, but have no success.

I have tried to modify the code using the following, but the result just posts a "-1" in my alert popup.

As you can see I modified the code from the original thread in the third block of "for" code. also, I added an "alert" tag. One more thing, I added a function call for the form button.

The code is below:

<script type="text/javascript">
var count = 0;
var itemList = new Array();
var oldText = "";

[Code]....

Determine FORM That Contains A Specific INPUT Element?

Oct 11, 2006

I created this test routine to return the form containing a certain
input element:

function GetElementForm(element)
{
// Return the form that contains element.

varmyElement = element;

while (myElement)
{
myElement = myElement.parentNode;
if (myElement)
{
var sTagName = myElement.tagName;
if (sTagName)
{
if (sTagName.toLowerCase() == "form")
{
break;
}}}}
return myElement;}

This seems to work for "well formed" HTML, but fails for example, when
a form is defined within a table.

Nov 5, 2009

Within a classic asp webform (using vbscript) I would like part of the form (input boxes within table structure) to be specific/displayed depending on the users selection from the combo box in the row above.

JQuery :: Dynamically Generate Specific Numbers Of Form Input Fields?

Sep 22, 2010

I am not new to jQuery but I just want to ask the best way to approach this. Basically I have a textfield in which the user is going to type in a number (for example 20) and after this textfield lose focus jQuery will be triggered to create whatever number of textfields the user put before (in this case 20).

So, to illustrate: How many users do you have: [ 2 ](and after the field above lose focus, the below will be generated)

Fullname: [ ]
Fullname: [ ]

JQuery :: Select A Specific Class Inside A Specific Div Based On The ID From A Button Elsewhere On The Page

Mar 10, 2010

<div class="box top"></div>
<div class="box main">
<div class="box header">
<div class="badge"><ul><li class="active"><span>60</span></li></ul></div>

[Code]....

What is happening is $(this) is no longer based on .expand being the (this) that is clicked.

like if i have a button SOMEWHERE randomly on the page with this

<div onclick="Minimize('_alerts');">Click Here</div> this will minimize alerts but because the (this) in minimize function doesn't actually point to the right button that I want to add a class to.

Is there a way to modify the minimize function so that it finds the <div id="mytoggle"><ul> <li class="expand boxminimize" rel="_alerts"> using the rel toggle, and then changes the class of the li from expand boxminimize to boxexpanded??

just like the .expand click function I posted on the top of the post that works?

Browser Detect To Load Specific Code For Specific Browsers?

Oct 6, 2009

Another thing that has been driving me crazy is that css positioning is handled differently by different browsers. JS is not my area, but I can do a lot with CSS, and I do, but cross browser compatibility is killing me.

I can use an IF IE statement and only IE runs that segment of code, but I haven't been able to figure out out how to make ONLY firefox or ONLY opera or safari enact an encapsulated segment of code. The same type of IF statement doesn't work for them.

Is there a single method using JS that works for all browsers?

JQuery :: Two Input Fields / Give Second Input Field Always Same Value As Input Field One

Jun 7, 2010

I am having a form with two input fields. I want to enter some text in the first input field and then the second field should get the same text. Is there a simple way (maybe a plugin) to do this with jQuery? It would be perfect if I even could output all these input fields values as normal text in <p> or <li> tags.

JQuery :: 'input:text' Selector Not Finding Input Element With No Type Attribute?

Mar 16, 2011

As recently as 1.4.3 $('input:text') would find input elements with no type attribute, but after upgrading to 1.5.1 that is no longer the case.

Is this a bug or an intended refactor to be more standards compliant?

FYI - this is the selector I now have to use: $('input:text,input:not([type])')

JQuery :: Limiting Character Input - Also Displaying Input Fields Contents

Sep 7, 2009

I have a pretty basic set of things I want to do: Capture key press, compare against an allowed list, block keys that are not in that list, replace a space by a dash if entered. As this is happening, I have a span I wanted to be updated with the live values. The username field at [URL] is exactly what I am trying to do, though I have trouble dissecting how they did it. Here is my attempt, which is off by one keypress for some reason.

AJAX :: Populate The Third Input In The Same Row As The Second Input Based Upon A Separate Db Query?

Oct 29, 2010

I've got a form in which the fields are being dynamically generated based upon a db query.. it looks something like this:

Code:

<form name="bft">
<input name="colA_1"> <input name="colB_1" onBlur="loadXMLDoc(this.value,'colC_1');"><input name="colC_1">

[code]...

I'm trying to use AJaX to populate the third input in the same row as the second input based upon a separate db query. Here's the code for that:

Code:

<script type="text/javascript">
function loadXMLDoc(v,n) {
if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari

[code]...

Here's where it displays on the page<cfoutput>#trim(getITRRSP.[columnName])#</cfoutput>
Whenever the focus blurs from those inputs, the third column in that row is populated with "UNKNOWN" as the value. I have confirmed that the getITRRSP.cfm file is properly retrieving and displaying the data from the db query.
