我在访问变量时遇到了一些麻烦,在这种情况下是 Setvariable。当我进入循环时,变量不存在。任何人都对此有任何见解。感谢你的帮助

下面是我在模板中的代码部分。当你有机会时,你会帮忙吗?谢谢。

<!-- TemplateBeginRepeat name="Component.Fields.section" -->
@@SetVariable("columnSectionIndex", "${TemplateRepeatIndex}")@@
Inline Value @@GetVariable("columnSectionIndex")@@       Variable value can be accessed
    <!-- TemplateBeginRepeat name ="Field.links" -->
      Inside Loop Value @@GetVariable("columnSectionIndex")@@  //Not getting declared           variable //value here. Says variable doesn’t exist in ContextVariables.
       <!-- TemplateBeginRepeat name ="Field.linkimages" -->
       <!-- TemplateEndRepeat -->
    <!-- TemplateEndRepeat -->
<!-- TemplateEndRepeat -->

输出

Variable Added Successfully
Inline Value 0 
Inside Loop Value Variable doesn't exist 

我的载重吨代码

[TemplateCallable()]
public string SetVariable(string variableName, string value)
    {
        //Remove the old variable and set the new variable
        if (_Engine.PublishingContext.RenderContext.ContextVariables.Contains(variableName))
        {
            _Engine.PublishingContext.RenderContext.ContextVariables[variableName] = value;
            return "Variable Modified Successfully";
        }
        else
        {
            _Engine.PublishingContext.RenderContext.ContextVariables.Add(variableName, value);
            return "Variable Added Successfully";
        }
    }
    [TemplateCallable()]
    public string GetVariable(string variableName)
    {
        //Get the varialbe
        if (_Engine.PublishingContext.RenderContext.ContextVariables.Contains(variableName))
            return _Engine.PublishingContext.RenderContext.ContextVariables[variableName].ToString();
        else
            return "Variable doesn't exist";
    }

循环中的变量问题是众所周知的,甚至被记录在案

基本上,第一个循环已经在您设置变量时进行了评估,因此您总是会落后一个。

  • 设置变量 i=0
  • 循环迭代 1,i=null
  • 循环迭代 2,i=0
  • 循环迭代 3,i=1
  • ETC
