分配查詢結果變量和在javascript

Question

<script type="text/javascript"> 
$('x').load("https://blockchain.info/q/getreceivedbyaddress/1Pt9TRJKeAW61aR1ELQpUZKdMaYXzkCTrn",function(){ 
    var formatted_value=$('x').text();//$('**x**') is selector for the class 
    var goalGauge = new Gauge(); 
    goalGauge.draw(formatted_value); 
}); 
</script> 
<canvas id="gauge" width="240" height="240" style="display: block; width: 240px; margin: 0px auto;"></canvas></div> 

的查詢中使用它發送其被用於填充計的數目。如何將收到的值分配給var formatted_value？

它現在有效。該代碼是：

<div style="width: 100%; float: left;"> 
<div id="x"></div> 
<canvas id="gauge" width="240" height="240" style="display: block; width: 240px; margin: 0px auto;"></canvas> 
</div> 
<script type="text/javascript"> 
$('#x').load("https://blockchain.info/q/getreceivedbyaddress/1Pt9TRJKeAW61aR1ELQpUZKdMaYXzkCTrn", function() { 
var formatted_value = $('#x').text(); //$('**x**') is selector for the class 
var goalGauge = new Gauge(); 
goalGauge.draw(formatted_value); 
}); 
</script>

負載是異步的話，

$('**x**').load("https://blockchain.info/q/getreceivedbyaddress/********",function(){ 
     var formatted_value=$('**x**').text();//$('**x**') is selector for the class 
     var goalGauge = new Gauge(); 
     goalGauge.draw(formatted_value); 
});
