Spring Mvc - Update Fusioncharts From Ajax Response.

deepti · December 14, 2011

Hi,

I am trying to integrate spring mvc with ajax.I want to get the chart xml and swf from ajax response and set it to the chart and display the chart.The call back function is getting called and I can see the xml in the firebug response object . Even though I have provided the swf and xml the chart is not getting loaded initially also.I am not sure if the FusionChartsRenderer.jsp is getting included in the page because I am not able to see as if it is included when I see the firebug response when the page is initially loaded.And in the updateChart function getChartFromId("FactorySum") is returning null.I have the fusionchart.js file in classpatha nd it is getting loaded also. Pls help.

Following is my jsp code :

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

<%@ taglib prefix="tags" tagdir="/WEB-INF/tags"%>

<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>

<%@ page session="false"%>

<tags:template>

<jsp:attribute name="breadcrumb">Plant View</jsp:attribute>

<jsp:body>

<table border="0" cellpadding="0" cellspacing="0" width="100%"

id="qdtable">

<c:forEach items="${qd_List}" var="qdItem">

<td width="220" style="text-align: center; vertical-align: middle"

id="qdtabletd1">

${qdItem.source}</td>

<td

style="vertical-align: middle; horizontal-align: right; width: 350px;"

id="qdtabletd2">${qdItem.metric}</td>

<form:select id="${qdItem.id}" path="qd_List"

items="${qdItem.timePeriodList}" /></td>

<td><a href="#" id="executeChart">Execute</a></td>

</tr>

</c:forEach>

</table>

<jsp:include page="FusionChartsRenderer.jsp" flush="true">

<jsp:param name="chartHeightStr" value="300" />

<jsp:param name="debugModeStr" value="true" />

<jsp:param name="registerWithJSStr" value="true" />

</jsp:include>

<BR>

<a href='./html/NoChart.html' target="_blank">Unable to see the chart above?</a>

</div>

</jsp:body>

</tags:template>

jq(document).ready(function() {

jq('#qdtable tbody tr td #executeChart').click(function () {

jq(this).closest('tr').find("select").each(function() {

getQualityMetricChart(this.id,this.value);

});

function getQualityMetricChart(id,tmPeriod) {

jq.getJSON("pview/getChart", {id:id,timePeriod:tmPeriod}, function(success) {

alert("callback");

jq('#chartIdDiv').html("<span id='chartFS'>" + success.swfPath + "</span>");

updateChart(success.chartXml,success.swfPath)

});

function updateChart(xml,swf){

alert('up');

var chartObj = getChartFromId("FactorySum");

chartObj.setSWFPath(swf);

chartObj.setDataXML(xml);

}
