【问题描述】：

我在 Django 模板中使用 JS，但 JS 代码没有响应。怎么办？

这里面<script>标签：

 var pageStrucVal =  pagestruc ;
        if (pageStrucVal >= 82)
            var pageWarn = ["Brilliant, your site's structure and design is awesome and rocking. <gold>RockingStructure</gold>", 'pp']
        
            
        else if ( pageStrucVal >= 72)
            var pageWarn = ["Nice, your site's structure and design is suitable", 'pp']
            
            
        else if ( pageStrucVal < 45)
            pageWarn = ["Extremely bad condition, your site's structure and design is extremely bad and unmanaged. Strictly to use a different theme or change the interface (UI). <red>#ExtremelyBad</red>", 'dd'];
            
        else if ( pageStrucVal < 50)
            pageWarn = ["Worst conditon, the content quality of your site is too much poor. Use a well-managed theme or change the interface (UI).<orange>#ReallyPoor</orange>", 'dd'];
            
        
        else if ( pageStrucVal < 55)
            pageWarn = ["Too much bad, your site's structure and design is too much bad and unmanaged. Try to use a different theme or change the interface (UI).<orange>#VeryPoor", 'dd'];
            
        
        else if ( pageStrucVal < 63)
            pageWarn = ["Very bad, your site's structure and design is very unmanaged. You can try to use a different theme or change the interface (UI).<orange>#MuchBad</orange>", 'dd'];
            
        
        else if ( pageStrucVal < 72)
            pageWarn = ["Bad, your site's structure and design isn't suitable. Small change in the interface (UI) is required.<green> #TendsToBad</green>", 'dd'];
            
        console.log(pageWarn);
        document.getElementById(pageWarn[1]).appendChild(document.createElement('p')).innerhtml = (pageWarn[0]);
    

document.getElementById(pageWarn[1]).appendChild(document.createElement('p')).innerHTML = (pageWarn[0]); 的书写和位置是否正确？

这是 HTML：

<div class='plusNdefects' id='moredetails'>
            <h1>Good Aspects and Plus Points.</h1>
            <p class='details'>Here are some awesome good aspects and benefits you have in your site to get Google Adsense.</p>
        
            <!-- Ads ::> -->
            % include "ads/outads.html" %
            <!-- Ads <:: -->
        
            <div class='persona'>
                <div id='pp'> </div>
            </div>
        </div>
        
        <div class='plusNdefects'>
            <h1>Disabilities and Improvements.</h1>
            <p class='details'>These are some disabilities of your website that are stopping you from being approved by Google
                Adsense.</p>
        
            <!-- Ads ::> -->
            % include "ads/outads.html" %
            <!-- Ads <:: -->
        
            <div class='persona'>
                <div id='dd'></div>
            </div>

'pp' 和 'dd' 是我要插入消息的 id（位置）。 “pp”代表加分，“dd”代表缺陷。

【问题讨论】：

什么意思？你能详细说明你想做什么吗？

它没有给出任何结果。数组pageWarn[1] 的最后一个元素是div 标签的id，我想将消息插入到索引为0 的div 标签内，即pageWarn[0]。

能否请您发布您的完整html？

请看一下。我已经发布了。

您的 html 和 javascript 看起来不错。 pagestruc 返回的是什么？您是否尝试将 pagestruc 替换为任何其他整数值？

【参考方案1】：

我认为 django 标签之外的用户 qoutes 是一个更好的主意。var pageStrucVal = parseInt(' pagestruc ');

【参考方案2】：

试试var pageStrucVal = parseInt( pagestruc );

【讨论】：

它按照你的想法工作。 var pageStrucVal = parseInt( pagestruc ); 是正确答案。

这意味着检查绿色对勾按钮。对不起，我是菜鸟。如果“是”，我已经完成了。

你的另一个好处。你能帮我减少代码的长度吗？

对不起，我看不出哪里可以简化。您可以使用 javaScript minifier 或其他一些工具来缩小它。
