Question

我必须使用javascipt在标签之间注入以下给定的脚本。

<script>
!function(f,b,e,v,n,t,s){if(f.fbq)return;n=f.fbq=function(){n.callMethod?
n.callMethod.apply(n,arguments):n.queue.push(arguments)};if(!f._fbq)f._fbq=n;
n.push=n;n.loaded=!0;n.version='2.0';n.queue=[];t=b.createElement(e);t.async=!0;
t.src=v;s=b.getElementsByTagName(e)[0];s.parentNode.insertBefore(t,s)}(window,
document,'script','https://connect.facebook.net/en_US/fbevents.js');

fbq('init', '1234');
fbq('track', "page");</script>
<noscript><img height="1" width="1" style="display:none"
src="https://www.facebook.com/tr?id=1234&ev=page&noscript=1"
/></noscript>

我试过了，

        var head = document.getElementsByTagName('head')[0];
        var script = document.createElement('script');
        script.innerHTML = "!function(f,b,e,v,n,t,s){if(f.fbq)return;n=f.fbq=function(){n.callMethod?n.callMethod.apply(n,arguments):n.queue.push(arguments)};if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';n.queue=[];t=b.createElement(e);t.async=!0;t.src=v;s=b.getElementsByTagName(e)[0];s.parentNode.insertBefore(t,s)}(window,document,'script','https://connect.facebook.net/en_US/fbevents.js');fbq('init', '1234');fbq('track', "page");";
        head.appendChild(script);

但它不起作用。我怎么能这样做？

您需要在var head = document.getElementsByTagName('head')[0]; var script = document.createElement('script'); script.innerHTML = "!function(f,b,e,v,n,t,s){if(f.fbq)return;n=f.fbq=function(){n.callMethod?n.callMethod.apply(n,arguments):n.queue.push(arguments)};if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';n.queue=[];t=b.createElement(e);t.async=!0;t.src=v;s=b.getElementsByTagName(e)[0];s.parentNode.insertBefore(t,s)}(window,document,'script','https://connect.facebook.net/en_US/fbevents.js');fbq('init', '1234');fbq('track', \"page\");"; head.appendChild(script);附近的结尾处转义引号：

Array
(
    [LegendID] => 1
    [XData] => 21/05/2016
    [YData] => 10
)
Array
(
    [LegendID] => 1
    [XData] => 22/05/2016
    [YData] => 25
)
Array
(
    [LegendID] => 1
    [XData] => 23/05/2016
    [YData] => 30
)
Array
(
    [LegendID] => 2
    [XData] => 21/05/2016
    [YData] => 43
)
Array
(
    [LegendID] => 2
    [XData] => 22/05/2016
    [YData] => 54
)
Array
(
    [LegendID] => 2
    [XData] => 23/05/2016
    [YData] => 96
)
Array
(
    [LegendID] => 3
    [XData] => 21/05/2016
    [YData] => 56
)
Array
(
    [LegendID] => 3
    [XData] => 22/05/2016
    [YData] => 78
)
Array
(
    [LegendID] => 3
    [XData] => 23/05/2016
    [YData] => 65
)
