jQuery CSV plugin won't split rows into arrays-of-arrays
I am trying to use the jQuery "CSV" plugin, as documented here: http://code.google.com/p/js-tables/wiki/CSV
According to the documentation:
// Convert CSV data into array of arrays
jQuery.csv()("1,2,3\n4,5,6\n7,8,9\n"); // = [ [1,2,3], [4,5,6], [7,8,9] ]
But when I attempt to do something similar, it just seems to treat the "\n" as another character in the middle of an array element.
What am I doing wrong? I am using jQuery 1.4.2 and Firefox 3.5.10 for testing. I have also tried it with jQuery 1.3 and get the same result.
If it is a problem with the plugin, then can someone suggest another plugin for reading CSV? My ultimate goal is to convert CSV from a string into an HTML table; the only plugin I can find that specifically does this requires the CSV to come from a file, which is not desirable for my task.
Here is a minimal test page I put together which illustrates that it's not separating the lines into sub-arrays:
<html>
<head>
<title>CSVtest</title>
<script type="text/javascript" src="jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="jquery.csv.js"></s开发者_如何学编程cript>
<script type="text/javascript">
$(document).ready(function() {
var lines = $.csv()("a,b\nc,d");
alert(lines[0][1]); // Displays: b
// c instead of the expected b
});
</script>
</head>
<body>
</body>
</html>
Make sure you're using the latest version of the plugin. I copied and pasted your example using jQuery 1.4.2 and the (now outdated) CSV plugin from http://js-tables.googlecode.com/svn/trunk/jquery.csv.min.js and it works fine.

Tested in IE8, IE6, Google Chrome and Firefox. I also tested
alert(lines[1][1]);
and sure enough, the alert displayed "d".
If you only deal with simple data (no quotation) you can do something like this:
function csv(text) {
var lines = text.split("\n");
for ( var i = 0; i < lines.length; i++ ) {
if (!lines[i])
lines.splice(i, 1);
else
lines[i] = lines[i].split(",");
}
return lines;
}
加载中,请稍侯......
