基于Handlebar工具为谷歌应用调整状态显示的条件判断逻辑

Alright, let's tweak your Handlebars template logic to meet the new requirement. You need to show "Pending" not just when isPendingState() returns true, but also when empObj.Current_Appraisal_State is null or empty. Here are a couple of clean ways to implement this:

Option 1: Using Built-in Logical Helpers (if available) #

If your Handlebars setup includes the or and not helpers (common in many extended implementations like Handlebars.js with extra utilities), you can combine both conditions into a single if block:

{{~#if (or (isPendingState) (not empObj.Current_Appraisal_State))}}
  Pending
{{~else~}}
  {{~empObj.Current_Appraisal_State~}}
{{~/if~}}

How this works: #

• (isPendingState) checks your original pending state condition
• (not empObj.Current_Appraisal_State) evaluates to true if empObj.Current_Appraisal_State is null, undefined, or an empty string (Handlebars treats all these as "falsy" values)
• The or helper returns true if either condition is met, triggering the "Pending" display; otherwise, it shows the existing appraisal state

Option 2: Nested Conditionals (no extra helpers needed) #

If your environment doesn't have access to logical helpers like or/not, you can use nested if blocks to achieve the same result:

{{~#if (isPendingState)}}
  Pending
{{~else~}}
  {{~#if empObj.Current_Appraisal_State}}
    {{~empObj.Current_Appraisal_State~}}
  {{~else~}}
    Pending
  {{~/if~}}
{{~/if~}}

How this works: #

1. First, check if isPendingState() is true — if yes, show "Pending"
2. If not, check if empObj.Current_Appraisal_State has a truthy value (not null/empty) — if yes, display that value
3. If neither condition is met, fall back to showing "Pending"

Bonus: Handling Whitespace-Only Values #

If empObj.Current_Appraisal_State might contain only whitespace (like " ") and you want to treat that as empty too, you'll need a custom trim helper. Once registered, you can adjust the condition to:

{{~#if (or (isPendingState) (not (trim empObj.Current_Appraisal_State)))}}
  Pending
{{~else~}}
  {{~empObj.Current_Appraisal_State~}}
{{~/if~}}
