I have a for loop: Code: for( var i = 0; i < aInput.length; i++ ) I want to use this i variable to concatonate it as a string to find an input box
Code:
var j = i;
var qualname = "discountqualifier" + j;
qualname.toString();
if ( inputName == ( qualname ) )
{
Assuming I have a input box named discountqualifier0, discountqualifier1, discountqualifier2 etc...
I have a javascript program that currently takes the contents of a *.txt file and converts it to a string-type variable using a hidden iframe.
For my pruposes it would be much nicer to read a *.csv file instead, however the method I'm using creates the "open/save file" pop-up window.
All files are client-side and in the same folder on one computer; this is NOT server-side or internet-based. It is simply javascript used in an HTA file as programming code. The *.csv does not need to be edited, just read.
I need to know how to convert the text of this *.csv file into a string variable. I have heard of using "xmlHTTPRequest (AJAX)" but am not familiar with how to use this.
i'm trying to concatenate to a string 2 variables that i'm adding together but i'm getting Nan as the result
what am i doing wrong?
str_amount=parseInt(document.getElementById('amount').value);
strfeeamount=parseInt(document.getElementById('feeamount').value);
urltoajax=urltoajax + '&amount=' +str_amount +strfeeamount
I am having some trouble getting an email form to work correctly. I am looking to convert some text from a text area into some basic HTML so I can insert breaks then email it.
So when the user clicks submit ... the string is taken from the textarea and converts the linebreaks into <br> tags.
The problem is not replacing the text, it is finding the line breaks I have no Idea how Code:
Is there a javascript method or whatever to convert a string to one
that is valid for http transmission?
One that converts characters like " " to %20 || < to <: etc
I am after an encompassing javascript line like:-
msg = msg.replace( whatever, http_equivalent );
Well, I need some light in this simple thing I'm trying to do. I'm
using the XMLHttpRequest to retrieve some data from a db via php
script. The result is passed to a "results" array of strings, which
contain the data from the script.
But, the data from the script, which are the content of the strings,
have html tags in it. The thing is: I'm using the DOM to append the
string result to a table already built in the page (using
create_element and appendchild).
insertO = document.getElementById("output_table");
oTR = document.createElement('tr');
oTD = document.createElement('td');
oText = document.createTextNode(Text);
oTD.appendChild(oText);
oTR.appendChild(oTD);
insertO.tBodies[0].appendChild(oTR);
The Text var would contain something like "<font color="red">this
<b>is</b> html</font>".
This way the output isn't parsed, i.e., it shows the tags.
Does anyone have an idea on how to overcome this?
I have searched the web and this forum for the answer to this but am unable to find a reasonable choice. So, this is the problem I am facing.

I know the easiest way to do this is to use eval() and it most definitely does work. The problem is that I have to use eval() inside a loop to check whether the reference is null and from what I hear, that is one of the most inefficient ways to code. I have searched for alternatives like using, var myFunc = new Function(string) and then calling myFunc(). But this does not work in my case. I cannot find any other alternative in this case. I guess one can say eval() is the only choice here but I am not too sure.
I have a good HTML markup parsing function which uses DOM methods to create element nodes with attributes and contained text nodes. But for some reason I am having difficulty getting the event handler attribute value (which is javascript code) converted to actual source.
[Code]...
But when I click on the button in Firefox, nothing happens. Using a Javascript debugger, the trace doesn't even enter the handler code, which effectively means the event listener has no script.
So converting the code-as-string to code-as-source using the Function constructor is not working. Or else the event handler setting function or assignment is not what it should be.
Let me preface this with the usual disclaimer: I am new to this and have only been programming with Javascript, PHP for about 2 weeks now and have been lucky enough to have resolved the issues I have encountered. This one however is puzzling to me.
I have a HTML form created that collects member information. It calls, on submit, a confirmation page that lists all the data fields entered. This all works great. However, when I then post the variables from the first html form page from my second confirmation html page to my PHP script, using document.write with input type=hidden and inserting the address variable into the value field, the Javascript only passes this variable up to the first space. It is the only variable I pass that has a space in it.
I have verified that the variable does indeed contain the whole address and I have also verified when I execute the following: document.write ('<input type="hidden" name="address1" value='+address_1+'>');
the address_1 parameter passed to the php script only passes the string up to the first space.
I even tried to put fixed text in there instead of a variable (e.g.)
document.write ('<input type="hidden" name="address1" value="555 Drury Lane" >');
and it still only passes the string up to the first space (555).
I show the variable address_1 on my confirmation page and it shows the entire string.
I checked what was being passed and it seems that the Javascript is the culprit (or more likely the Javascript creator - me)
All my other variables (which don't have spaces) pass to the php script with no problems.
I have an Adobe pdf fill-able form field that requires a distance computation using javascript. One of the values needed in the computation is in the format of a string as feet - inches (for example: 4'-10"). I need to convert this into a number to use to complete a computation. Any code snippet or ideas on how to do this.

View 2 Replies View RelatedI think this is a problem converting (what is assumed to be) a string to numeric. or something like that.
rvs = s[i][j] * k;
Firefox Error Console says:
Uncaught exception: TypeError: Cannot convert 's[0]' to object
rvs is just a (temporary, holding) variable.
s is a [3][6] array on numeric values.
i, j and k all happen to be zero.

Tool for converting between JSON and string back and forth? I don't want to use a framework like Prototype just for this so ideally umm, no frameworks please lol
Also on a side note, the eval function doesn't seem to be able to convert all possible JSON strings into an object for some reason. It only works for simple JSON literals.
jQuery noob here, so I apologize in advance if this question has been asked before. My situation is this: I have a string of HTML that I've extracted from my document and passed into jQuery to manipulate as such:
Code:
var pageEl = document.getElementById("ElementId");
var contentToProcess = pageEl.innerHTML;
// pre-process contentToProcess...
var jQueryContent = $(contentToProcess);

I'm trying to accomplish the following, preferably using jQuery, find this string on a page (it occurs only once).. 'BC-' and then, depending on the page i'm on either - add a simple <br/> tag before it, or enclose in it within a span tag with a class. adding the span would be more complicated because 3 numbers follow the BC- ex: BC-103.

I'm trying to learn jQuery and am currently attempting to clone a div and then find and replace part of a string. The cloning part works, but I can't seem to get it to alter the text...

Just a quick one here I want a regular expression that tests a string to find out if not empty. I am currently using /^[a-zA-Z0-9]+$/ which allows all alphanumeric characters, however unfortunately does not allow white space. As I am trying to use the RE for a form name input and I don't wish to separate first and last name, I want to allow users to enter their full name including spaces. Can anyone tell me an RE that allows all alphanumeric characters and white space in a string but does not allow an empty string

Unfortunately that doesn't work. I understand that the index() isdocumentation (though confusing) correctly tells you that the above code doesn't work. Maybe I'm just weird, but I feel that the way .index() is implemented for string arguments is very counter intuitive. I have an expectation that .index() is similar to indexOf() in javascript.
