    <p>I have to edit my question just to make it clear. What I need to do is attach the value of startdate and enddate on this jsonData.php.</p> <p>If the text field is empty, the defaul values will show, but if not..startdate and endate values should be what was entered by the user.</p> <pre><code> &lt;script type="text/javascript"&gt; var startdate = "2012-01-01"; var enddate = "2012-01-06"; var jsonData = $.ajax({ url: "jsonData.php?startdate="+ startdate +"&amp;enddate="+ enddate, dataType:"json", async: false }).responseText; </code></pre> <p>MY Text field code:</p> <pre><code>Start Date: &lt;input type="text" name="startdate" id="startdate"/&gt; End Date: &lt;input type="text" name="enddate" id="enddate"/&gt; </code></pre> <p>I tried using this code, but it didnt work:</p> <pre><code>var startdate = "2012-01-01"; var enddate = "2012-01-06"; if (document.getElementById('startdate').value == ''){ startdate = "2012-01-01"; } else{ startdate = document.getElementById('startdate').value; } if (document.getElementById('enddate').value == ''){ enddate = "2012-01-06"; } else{ enddate = document.getElementById('enddate').value; } </code></pre> <p>Im getting that error because I have declared the variables on separate script tags. How will i Fix this. <img src="https://i.stack.imgur.com/8QAT8.jpg" alt="enter image description here"></p> <p>UPDATE 2: Whole code:</p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt; &lt;head&gt; &lt;meta http-equiv="content-type" content="text/html; charset=utf-8"/&gt; &lt;script type="text/javascript" src="https://www.google.com/jsapi"&gt;&lt;/script&gt; &lt;link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css" rel="stylesheet" type="text/css"/&gt; &lt;script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"&gt;&lt;/script&gt; &lt;script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; google.load('visualization', '1', {'packages':['corechart','piechart']}); &lt;/script&gt; &lt;script type="text/javascript"&gt; $(document).ready(function() { $('.date').datepicker({dateFormat: "yy-mm-dd"}); var startDate = $('#startdate'); var endDate = $('#enddate'); if (startDate.val() == '') { startDate.val('2012-01-01'); } if (endDate.val() == '') { endDate.val('2012-01-06'); } }); var pieJsonData = $.ajax({ url: "overall_calls_forms_pos_pie.php", dataType:"json", async: false }).responseText; var pieData = new google.visualization.DataTable(pieJsonData); var pieJsonData2 = $.ajax({ url: "overall_ban_pos_pie_date.php?startdate="+ startdate +"&amp;enddate="+ enddate, dataType:"json", async: false }).responseText; var pieData2 = new google.visualization.DataTable(pieJsonData2); function pieChart() { pieChartWrapper = new google.visualization.ChartWrapper({ 'chartType': 'PieChart', 'containerId': 'pie_div', 'dataTable':pieData, 'options': { chartArea:{left:10,top:40,height:200,width:300}, width:360, height:260, title: "Positive Contacts Percentage", titleTextStyle:{fontSize:14}, tooltip:{showColorCode:true}, legend:{textStyle:{fontSize: 12},position:'left'}, pieSliceTextStyle:{fontSize: 12} } }); google.visualization.events.addListener(pieChartWrapper, 'ready', pieReady); pieChartWrapper.draw(); } function pieReady() { // Change the pie chart rendering options when clicked. document.getElementById('optionsButton').onclick = function() { pieChartWrapper.setDataTable(pieData2); pieChartWrapper.draw(); }; document.getElementById('optionsButton2').onclick = function() { pieChartWrapper.setDataTable(pieData); pieChartWrapper.draw(); }; } google.setOnLoadCallback(pieChart); &lt;/script&gt; &lt;/head&gt; &lt;body&gt; Start Date: &lt;input type="text" name="startdate" class="date" id="startdate"/&gt; End Date: &lt;input type="text" name="enddate" class="date" id="enddate"/&gt; &lt;div id="buttons"&gt; &lt;button style="margin: 2em" id="optionsButton"&gt;Get My Data 2&lt;/button&gt; &lt;button style="margin: 2em" id="optionsButton2"&gt;Get My Current Data&lt;/button&gt; &lt;/div&gt; &lt;div id="pie_div" style="float:left;"&gt;&lt;/div&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>I USED: to correct my mistake. But the chart doesnt redraw unless the page refreshes.</p> <pre><code> $(document).ready(function() { $('.date').datepicker({dateFormat: "yy-mm-dd"}); var startDate = document.getElementById('startdate').value; var endDate = document.getElementById('enddate').value; if (startDate == '') { startDate = ('2012-01-01'); } if (endDate == '') { endDate = ('2012-01-13'); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
