Jscript: Invalid character error !!

Recommended Posts

Hi,

I'm using a pie3d chart with drill down on all the pie pieces to build a bar chart as shown in the JS_dataurl example. When I click on the pie, I'm getting a "Line 1, character:15, Error: Invalid character" error. I tried in vain, but the code looks fine. Any help will be appreciated.

Thanks

All the data comes from a Oracle database.

Can you please run this code and let me have the final HTML output - as in this state, I do not see the links or data values.

Pallav,

I'm trying to pass a literal value to the drill down chart (link = updateChart(chgOrderID)). The literal string has a "#" in it. Example: "CO#7"

javascript gives an error saying "invalid character". I tried replacing the '#' with "HASH" and then reversing the same at the XML supplying page. it then says "COHASH7" is undefined.

here is the source:

I believe it's the set link which is causing a problem. Please try any of these variations to see if they work:

link='updateChart("CO#3");'

link="updateChart('CO#3');"

Basically, we're providing the parameter to updateChart function in quotes, as it's a string.

Pallav,

No luck with that. I'm having problems trying to fit the "quotes" in. It says "Invalid XML" when I try to move the quotations around like you suggested. This is the xml string that i'm building which is throwing an error.

this.strXMLDoc += "<set value='" + coAMT.ToString() + "' name='" + coID + "' color='" + colorArray[colorCount] + "' link='updateChart("+coID+")'/>";

Thanks for your help.

Since you've 3 nested quotes, you'll have to use ASCII code for one of them. Like, use the ascii code of " for the innermost quote.

Pallav,

I did replace them with ASCII, but I still get the "Invalid XML" msg.

this.strXMLDoc += "<set value='" + coAMT.ToString() + "' name='" + coID + "' color='" + colorArray[colorCount] + "' link='updateChart("+coID+")')/>";
this.strXMLDoc += "<set value='" + coAMT.ToString() + "' name='" + coID + "' color='" + colorArray[colorCount] + "' link='updateChart("+coID+")')/>";
this.strXMLDoc += "<set value='" + coAMT.ToString() + "' name='" + coID + "' color='" + colorArray[colorCount] + "' link='updateChart("+coID+")')/>";

Thanks

We use something like this in PHP:

$strLink = urlencode("updateChart(" . $intYear . "," . chr(34) . $ors['Country'] .  chr(34) . ");");

$strXML .= "<set label='" . escapeXML($ors['Country'], $forDataURL) . "' value='" . $ors['Average'] . "' link='" . $strLink . "'/>";

And something like this in ASP:

'Generate the link

 strLink = Server.URLEncode("updateProductChart(" & intYear & "," & oRs("MonthNum") & "," & ors("CategoryId") & ");")

 'Append data

 strDataXML = strDataXML & "<set value='" & oRs("Total") & "' link='" & strLink & "'/>"

Pallav,

I'm still getting the same error. "COHASH7" is undefined.

string coIDcoded = "COHASH7";
string strLink = Server.UrlEncode("updateChart("+coIDCoded+");");
this.strXMLDoc += "<set value='" + coAMT.ToString() + "' name='" + coIDCoded + "' color='" + colorArray[colorCount] + "' link='"+strLink+"'/>";

Thanks.
