html - 浏览器无法正确解析HTML-Grails 2

Question

我从 Controller (后端)生成HTML，但浏览器无法正确解析该HTML。
Controller 代码:

def getValue (returnIndex) {

        String dropDown = "<select name='" + returnIndex + "' style=''>"

        def CatArr = new BudgetViewDatabaseService().executeQuery("SELECT c.id,c.name AS categoryName FROM chart AS a LEFT JOIN crtClass AS b ON a.id=b.chart_class_type_id LEFT JOIN chart_group AS c ON b.id=c.chart_class_id WHERE c.status=1")
       
 if (CatArr.size()) {
            for (int i = 0; i < CatArr.size(); i++) {
                def catId = CatArr[i][0]
                def ProductArr
                ProductArr = new BudgetViewDatabaseService().executeQuery("SELECT id,accountCode,accountName FROM bv.crtMsr where status='1' AND chart_group_id='" + catId + "'")
                if (ProductArr.size()) {
                    dropDown += "<optgroup label='" + CatArr[i][1] + "'>"
                    for (int j = 0; j < ProductArr.size(); j++) {
                        dropDown += "<option value='" + ProductArr[j][1] + "' >" + ProductArr[j][1] + "  " + ProductArr[j][2] + "</option>"
                    }
                    dropDown += "</optgroup>"
                }
            }
        }

        dropDown += "</select>"
        return dropDown
    }

查看页面的代码:

<div class="fieldContainer fcCombo">
      <label>
              My GL <b>:</b>
     </label>
  
    ${new CoreParamsHelperTagLib().getValue('formFourGLAccount')}
</div>

问题:

生成的HTML看起来像:

当我从浏览器以编辑模式打开该HTML时，其外观如下:

    <select name='formFourGLAccount' style=''><optgroup 
label='Overige immateriële bezittingen'><option value='0430' >0430  Overige niet 
materiële bezittingen</option></optgroup><optgroup label='Computers en 
computerapparatuur'><option value='0210' >0210  Computers en 
computerapparatuur</option><option value='0211' >0211  Afschrijving computers en 
computerapparatuur</option></optgroup><optgroup label='Overige materiële 
bezittingen'><option value='0250' >0250  Overige materiële 
bezittingen</option><option value='0251' >0251  Afschrijving overige materiele 
bezittingen</option></optgroup><optgroup label='Waarborgsommen'><option 
value='0300' >0300  Waarborgsommen</option></optgroup><optgroup 
label='Deelnemingen in andere bedrijven'><option value='0310' >0310  Aandeel of belang 
 in andere bedrijven</option></optgroup><optgroup label='Strategische langlopende 
beleggingen'><option value='0320' >0320  Strategische langlopende 
beleggingen</option></optgroup><optgroup label='Verstrekte langlopende leningen 
(hypotheek ed)'><option value='0330' >0330  Verstrekte langlopende leningen (hypotheek
 ed)</option></optgroup><optgroup label='Overige financiële 
bezittingen'><option value='0340' >0340  Overige financiële bezittingen</option></optgroup><optgroup label='Voorraad'><option 
          

          
                    

如果我从 Controller 复制返回结果(HTML)并将其手动粘贴到浏览器中，则它可以正常工作

您尚未显示HTML的呈现方式，因此尚不清楚具体如何解决它，但是正在发生的是内容已被HTML编码，如果您希望浏览器评估HTML标记，则不希望这样做。
基于评论的编辑:

<div class="fieldContainer fcCombo">
      <label>
              My GL <b>:</b>
     </label>

    ${new CoreParamsHelperTagLib().getGLAccountExpanseBudgetForReconcilationOthersDropDown('formFourGLAccount')}
</div>

没有充分的理由来创建一个标记库的实例。您应将标签作为GSP标签调用。
您将从 Controller 返回硬编码的HTML作为模型变量。那是个坏主意，但不是您要问的。如果您确实想这样做，则需要防止在GSP中对数据进行HTML编码。您可以在GSP中使用raw(your unescaped html code here)方法作为避免编码的一种方法。
