[英]How to run javascript function from $(document).ready()
我正在使用jsgantt庫在網頁上創建甘特圖。 問題如下。
變體1不起作用 ,而變體2正在起作用 。 顯示警報“開始”,而在功能createChartControl
未顯示警報“ Fin”。 因此,我無法弄清為什么Variant 1無法正常運行(即空白的DIV容器)並且Firebug不顯示任何錯誤消息。 非常感謝您的幫助。
變體1:
<script>
function createChartControl(htmlDiv)
{
alert("Start");
var g = new JSGantt.GanttChart('g',document.getElementById(htmlDiv), 'hour');
g.setShowRes(1); // Show/Hide Responsible (0/1)
g.setShowDur(1); // Show/Hide Duration (0/1)
g.setShowComp(1); // Show/Hide % Complete(0/1)
g.setCaptionType('Resource'); // Set to Show Caption (None,Caption,Resource,Duration,Complete)
g.setFormatArr("hours","minutes")
if( g ) {
// Parameters (pID, pName, pStart, pEnd, pColor, pLink, pMile, pRes, pComp, pGroup, pParent, pOpen)
// You can also use the XML file parser JSGantt.parseXML('project.xml',g)
g.AddTaskItem(new JSGantt.TaskItem(1, 'Add minutes/hours', '', '', 'ff0000', 'http://help.com', 0, 'Ilan', 0, 1, 0, 1));
g.AddTaskItem(new JSGantt.TaskItem(11, 'Add support for half days', '5/14/2009 14:00', '5/14/2009 15:30', 'ff00ff', 'http://www.jsgantt.com', 0, 'Ilan', 100, 0, 1, 1));
g.AddTaskItem(new JSGantt.TaskItem(12, 'Add minute view', '5/14/2009 16:00', '5/14/2009 17:00', '00ff00', '', 0, 'Ilan', 40, 0, 1, 1));
g.AddTaskItem(new JSGantt.TaskItem(13, 'Add hours view', '5/14/2009 16:00', '5/14/2009 17:00', '00ffff', 'http://www.yahoo.com', 0, 'Ilan', 60, 0, 1, 1));
g.AddTaskItem(new JSGantt.TaskItem(14, 'Add support for format options', '5/14/2009 18:00', '5/14/2009 19:00', '00ffff', 'http://www.yahoo.com', 0, 'Shlomy', 60, 0, 14, 1));
g.Draw();
g.DrawDependencies();
alert("Fin");
}
else
{
alert("not defined");
}
}
</script>
<script>
$(document).ready(function() {
createChartControl('schedule');
});
</script>
<div style="position:relative" class="gantt" id="schedule"></div>
變體2:
<div style="position:relative" class="gantt" id="schedule"></div>
<script>
var g = new JSGantt.GanttChart('g',document.getElementById('schedule'), 'hour');
g.setShowRes(1); // Show/Hide Responsible (0/1)
g.setShowDur(1); // Show/Hide Duration (0/1)
g.setShowComp(1); // Show/Hide % Complete(0/1)
g.setCaptionType('Resource'); // Set to Show Caption (None,Caption,Resource,Duration,Complete)
g.setFormatArr("hours","minutes")
if( g ) {
// Parameters (pID, pName, pStart, pEnd, pColor, pLink, pMile, pRes, pComp, pGroup, pParent, pOpen)
// You can also use the XML file parser JSGantt.parseXML('project.xml',g)
g.AddTaskItem(new JSGantt.TaskItem(1, 'Add minutes/hours', '', '', 'ff0000', 'http://help.com', 0, 'Ilan', 0, 1, 0, 1));
g.AddTaskItem(new JSGantt.TaskItem(11, 'Add support for half days', '5/14/2009 14:00', '5/14/2009 15:30', 'ff00ff', 'http://www.jsgantt.com', 0, 'Ilan', 100, 0, 1, 1));
g.AddTaskItem(new JSGantt.TaskItem(12, 'Add minute view', '5/14/2009 16:00', '5/14/2009 17:00', '00ff00', '', 0, 'Ilan', 40, 0, 1, 1));
g.AddTaskItem(new JSGantt.TaskItem(13, 'Add hours view', '5/14/2009 16:00', '5/14/2009 17:00', '00ffff', 'http://www.yahoo.com', 0, 'Ilan', 60, 0, 1, 1));
g.AddTaskItem(new JSGantt.TaskItem(14, 'Add support for format options', '5/14/2009 18:00', '5/14/2009 19:00', '00ffff', 'http://www.yahoo.com', 0, 'Shlomy', 60, 0, 14, 1));
g.Draw();
g.DrawDependencies();

更新1:我應該說,當我使用dhtmlxGantt庫在函數createChartControl中創建圖表時,變體1正在工作。
更新2:我在變體1中更新了示例代碼。仍然無法正常工作-即顯示警報“開始”,而未顯示警報“ Fin”。
您確定從updateList獲得的響應是JSON對象嗎?
echo json_encode(array('a'=>'b'));
die();
如果您不響應JSON對象,請使用$ .get()方法。
PS:請不要使用'updateList.php?query ='+'DROP DATABASE()'嘗試一些MVC邏輯。
jsgantt需要全局變量g
才能起作用。 將var g
更改為window.g
。
所以看起來像這樣
變體1:
<script>
function createChartControl(htmlDiv)
{
alert("Start");
window.g = new JSGantt.GanttChart('g',document.getElementById(htmlDiv), 'hour');
g.setShowRes(1); // Show/Hide Responsible (0/1)
g.setShowDur(1); // Show/Hide Duration (0/1)
g.setShowComp(1); // Show/Hide % Complete(0/1)
g.setCaptionType('Resource'); // Set to Show Caption (None,Caption,Resource,Duration,Complete)
g.setFormatArr("hours","minutes")
if(g) {
// Parameters (pID, pName, pStart, pEnd, pColor, pLink, pMile, pRes, pComp, pGroup, pParent, pOpen)
// You can also use the XML file parser JSGantt.parseXML('project.xml',g)
g.AddTaskItem(new JSGantt.TaskItem(1, 'Add minutes/hours', '', '', 'ff0000', 'http://help.com', 0, 'Ilan', 0, 1, 0, 1));
g.AddTaskItem(new JSGantt.TaskItem(11, 'Add support for half days', '5/14/2009 14:00', '5/14/2009 15:30', 'ff00ff', 'http://www.jsgantt.com', 0, 'Ilan', 100, 0, 1, 1));
g.AddTaskItem(new JSGantt.TaskItem(12, 'Add minute view', '5/14/2009 16:00', '5/14/2009 17:00', '00ff00', '', 0, 'Ilan', 40, 0, 1, 1));
g.AddTaskItem(new JSGantt.TaskItem(13, 'Add hours view', '5/14/2009 16:00', '5/14/2009 17:00', '00ffff', 'http://www.yahoo.com', 0, 'Ilan', 60, 0, 1, 1));
g.AddTaskItem(new JSGantt.TaskItem(14, 'Add support for format options', '5/14/2009 18:00', '5/14/2009 19:00', '00ffff', 'http://www.yahoo.com', 0, 'Shlomy', 60, 0, 14, 1));
g.Draw();
g.DrawDependencies();
alert("Fin");
}
else {
alert("not defined");
}
}
