I 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.

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.
Code:
var str = "document.frames[0].document.frames[0]";
var str 1 = "document.frames[6]";
//Loop Starts
{
var obj1 = str + str1;

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.

View 14 Replies View RelatedI'm trying to wrap up my program now but cannot get it to stop at the right time. It should stop and print the report after the user enters "end" after being prompted to enter a course. I have do{}while loops in place. I also cannot seem to get it to store the amount of credits as totalCredits and the amount of points as totalPoints, which are necessary for the GPA formulaThe inputted Courses, Credits and Grade print out correctly but after typing "end" (in which it doesn't actually end but continues until you input the credit and grade for course "end" (which isn't a course)) it prints the Total Credits and Total "Quality Points" but the wrong GPA..The coding is almost the same as his, but I've tinkered with it for about 8hours straight now.

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 it possible to break apart a string into characters, be it a word or a sentence, and store each individual character in an array?

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.
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 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.
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 3 Replies View RelatedTool 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.
I have an XML file hosted by my ISP free web space. It naively treats
the file as text/plain. I would like to convert this data into a DOM
object. So far my googling has turned up nothing, although looking over
the DOM manual on Mozilla I came up with:
function convertDOM(text)
{
var lines = text.split("
");
var dom = document.createDocumentFragment();
for (var i = 0; i < lines.length; i++)
{
var node = document.createTextNode(lines[i]);
dom.appendChild(node);
}
return dom;
}
The returned object is not treated as an DOM object.
Anything I am missing / A different approach maybe?
I've been trying to create a 'loading page' for a from. When a user submitts a form, a loading animation is displayed on the page. Then I have javascript connecting to a url on my server that generates a dynamic file and returns it from memory. My problem is that I can display the text from this new file, but what I want to do is prompt the user to save the file locally. Is there a way to make this sort of conversion in javascript?

Say I had a bunch of elements with id names "id1", "id2". "id3" etc. Then say I had a function that adds a click handler such that when you click these elements it gets the id name with this.attributes[1].nodeValue;Then say I had a bunch of arrays with the same names as the ids var id1 = ["data", false, 45]; var id2 = ["otherdata", true, 15]; var id3 = ["otherotherdata", null, 65];. How would I set a variable "currentid" to the array with the corresponding name as the id name? I guess the underlying question is, how would I convert a string to a variable name?
