出於某種原因,我無法設置以字面形式創建的Javascript對象的適當位置。 使用PHP編寫Javascript代碼。第一個圖表對象chartObject1正確顯示,但第二個圖表chartObject2不顯示標題,因爲我試圖在文字定義之外設置標題文本屬性。無法設置Javascript對象屬性
爲什麼不讓我使用chartObject2.title.text = "chart2";
設置屬性?
<?php
$chart_text = <<<EOD
<script type="text/javascript">
var chartObject1 = Object;
$(document).ready(function(){
chartObject1 = new Highcharts.Chart({
chart: {
renderTo: 'chart1',
type: 'bar'
},
title: {
text: 'chart1'
},
xAxis: {
categories: ['Apples', 'Bananas', 'Oranges']
},
yAxis: {
title: {
text: 'Fruit eaten'
}
},
series: [{
name: 'Jane',
data: [1, 0, 4]},
{
name: 'John',
data: [5, 7, 3]}]
});
});
</script>
EOD;
print ($chart_text);
$chart_text = <<<EOD
<script type="text/javascript">
var chartObject2 = Object;
$(document).ready(function(){
chartObject2 = new Highcharts.Chart({
chart: {
renderTo: 'chart2',
type: 'bar'
},
xAxis: {
categories: ['Spiders', 'Grasshoppers', 'Scorpions']
},
yAxis: {
title: {
text: 'Bugs eaten'
}
},
series: [{
name: 'Jane',
data: [1, 0, 4]},
{
name: 'John',
data: [5, 7, 3]}]
});
chartObject2.title.text = "chart2";
});
</script>
EOD;
print ($chart_text);
?>
