问题描述

我需要修改$().SPServices.SPCascadeDropdowns，以便RelationshipList参数是动态的.我想更新relationshipList参数使用的GUID 根据所选的产品类型.

I need to modify $().SPServices.SPCascadeDropdowns so that the relationshipList parameter is dynamic. I want to update the GUID that the relationshipList parameter uses based on a Product Type selected.

更改产品类型"下拉列时将调用以下代码.但是，似乎没有 $().SPServices.SPCascadeDropdowns被调用.未对childColumn进行更新，以根据更新的RelationshipList显示新值.

The code below is called when the Product Type dropdown column is changed. However, it doesn't appear that$().SPServices.SPCascadeDropdowns is being called. The childColumn is not updated to display new values based on the updated relationshipList.

任何帮助将不胜感激. TIA

Any assistance would be appreciated. TIA

$("select [title ='Product Type']")).change(function(){
    var valGLBProductType = $(" select [title ='Product Type']).find('option:selected').text();

    if(valGLBProductType =='xyz){
   valViewID ="{GUID}";
    }其他{
   valViewID ="{GUID}";
    }

    $().SPServices.SPCascadeDropdowns({
   relationshipList:valViewID，
   relationshipListParentColumn:投标"，
   relationshipListChildColumn:"ActiveTitle"，
  &parentb:提案"，
   childColumn:要替换的文档"，
   调试:true
    });

    });

$("select[title='Product Type']").change(function() {
    var valGLBProductType = $("select[title='Product Type']").find('option:selected').text();

    if(valGLBProductType=='xyz){
   valViewID ="{GUID}";
    }else{
   valViewID = "{GUID}";
    }

    $().SPServices.SPCascadeDropdowns({
   relationshipList: valViewID,
   relationshipListParentColumn: "Proposal",
   relationshipListChildColumn: "ActiveTitle",
   parentColumn: "Proposal",
   childColumn: "Document To Replace",
   debug: true
     });

    });

推荐答案

relationshiplist值来自条件为select的更改事件，如果条件中缺少':

relationshiplist value comes from a select change event if condition, in the condition, there is a missing ':

if(valGLBProductType=='xyz')

请确保传递给RelationshipList的valViewID有效，您可以console.log这个变量来检查值.

And please make sure the valViewID passed to relationshipList is valid, You can console.log this variable to check the value.
