我有这个代码谷歌可视化API：
var slider;
var ajdi = '';
function drawVisualization() {
var cssClassNames = {
'headerRow': 'zaglavlje',
'tableRow': 'red',
'oddTableRow': 'red1',
'selectedTableRow': 'orange-background large-font',
'hoverTableRow': 'prekoreda',
'headerCell': 'gold-border',
'tableCell': 'cell',
'rowNumberCell': 'underline-blue-font'
};
var json = $.ajax({
url: 'getzadaci.php', // make this url point to the data file
dataType: 'json',
async: false
}).responseText;
// Create our data table out of JSON data loaded from server.
var data = new google.visualization.DataTable(json);
//dodajemo kolonu sa kontrolama
// Define a category picker control for the Gender column
var categoryPicker = new google.visualization.ControlWrapper({
'controlType': 'CategoryFilter',
'containerId': 'control1',
'options': {
'filterColumnLabel': 'Status',
'ui': {
'labelStacking': 'vertical',
'allowTyping': false,

},
view: {
// as an example, use columns "Naziv", "Vrsta", "Pocetak", and "Zavrsetak" for the timeline
columns: [8, 2, 5, 6]
},
});
var formatter_short = new google.visualization.DateFormat({formatType: 'short'});
formatter_short.format(data, 5);
formatter_short.format(data, 6);
new google.visualization.events.addListener(table, 'ready', function () {
google.visualization.events.addListener(table.getChart(), 'select', function () {
var selection = table.getChart().getSelection();
// iterate over all selected rows
for (var i = 0; i < selection.length; i++) {
$('#klikberba, #klikdjubrenje, #klikhemija,#kliksadnja').hide();
$('#sliderdj, #sliderh').slider({

}
//$("#edit").removeClass("edit btn btn-success")

// Create a dashboard
new google.visualization.Dashboard(document.getElementById('dashboard')).

bind([categoryPicker, categoryPicker1, categoryPicker2, slider, stringFilter1], [table, timeline]).
// Draw the entire dashboard.

function dashboardReady() {
// The dashboard is ready to accept interaction. Configure the buttons to
// programmatically affect the dashboard when clicked.
// Change the slider selected range when clicked.
document.getElementById('rangeButton').onclick = function() {
slider.setState({'lowValue': 2, 'highValue': 5});
slider.draw();
};
// Change the pie chart rendering options when clicked.
document.getElementById('optionsButton').onclick = function() {
piechart.setOption('is3D', true);
piechart.draw();
};
}
google.setOnLoadCallback(drawVisualization);// JavaScript Document
昨天我觉得一切正常.今天我收到这个错误：
Uncaught TypeError: Cannot read property ‘row’ of undefined on line 156.
我怎么能解决这个问题？
这是google viz API错误还是我在某处出现了syntacs错误？
解决方法:
我猜你的代码在这里失败了：
ajdi = table.getDataTable().getValue(selection[i].row,0);
看起来好像你在这一行之前关闭了你的for循环所以你的选择[i]将是未定义的
尝试将此行之前出现的括号}移动到选择[i]代码块之后
提示 – 尝试保持代码格式良好,以便您可以轻松查看ifs和fors的开始和结束位置 – http://jsfiddle.net/6JLfX/1/
