Hello,
I want to make a website that will let users input how they want to filter
the data view. I have everything working except the input. The user enters
how they want to filter the data into a HTML input box and the JavaScript
takes the input and evaluates the string as code using
new Function(input)
*input* is the variable that contains the string that the user entered.
ex.
view.getFilteredRows([{column: 1, minValue: new Date(2007, 0, 1)}])
This function is placed into the *setRows* method. And that is where it
breaks because for some reason, the evaluated string returns undefined.
Example of what my code looks like:
function filter(t) {
//instantiate data view
var view = new google.visualization.DataView(data);
// if query not empty, pass into 'new Function()' and then into
'setRows'
// if I don't add "view" argument, it tells me that view is undefined
if you have it in the query like the example
if (t.rowQuery.value) {
var rowQuery = new Function("view", t.rowQuery.value.split('/'));
view.setRows(rowQuery(view));
}
// draw data view
chart.draw(view, {allowHtml: true, showRowNumber: true});
}
I originally wanted to use Google's query, but I couldn't get it to work
for any other source except Google spreadsheet.
