Trying to retrieve data from user editable linear gauge
kennethdavid posted a topic in Using FusionWidgets XT
Hi I use the following code to try to get the pointer value from an editable linear gauge. The Jscript: <script language="javascript"> //FC_ChartUpdated method is called when user has changed pointer value. function FC_ChartUpdated(DOMId){ alert("in function"); alert(DOMId); //Check if DOMId is that of the chart we want if (DOMId=="myChartId"){ alert ("passed check"); //Get reference to the chart var chartRef = getChartFromId(DOMId); //Get the changed value var pointerValue = chartRef.getData(0); alert(pointerValue); } } </script> Currently the DOMId I pass in is the ID of the Chart object as per: var myChart = new FusionCharts("fusion/Charts/HLinearGauge.swf", "myChartId", "450", "120", "0", "0"); myChart.setDataURL("Data/Linear3.xml"); This is how I call the function to get the value: <input type="button" name="test" value="test" onClick="javascript:FC_ChartUpdated(myChartId)"> 2 Questions stem from this: 1. Upon clicking the button, I never get the alert "passed check" which means the DOMId isn't getting matched..... what am I doing wrong here? 2. How do I actually take the value and instead of putting it into an alert box, actually add it into the post or put variables when the form submits? is there a way to write it to the value of a hidden field? Thanks in Advance, Ken Thanks,
