如何直接从控制器向Grails中的JavaScript文件传递值 [英] How to pass a value directly from a controller to a javascript file in Grails

问题描述

想要直接从控制器传递给JavaScript文件。

TestControler.groovy

  def list（）{
渲染（view：list，model：[theId：theId]）
} 
  

Test.js

 函数test（）{
 //使用Id 
做$ sm} 
  

发现的解决方案在中间有已呈现的gsp，即这一个，但我想知道是否有办法避免这包括使用隐藏字段或在gsp文件中包含JavaScript代码片段，例如：

 < g：javascript> 
函数测试（$ {theId}）{
 //用
做$ sm 
< / g：javascript> 
  

解决方案

不幸的是，似乎没有任何内容涵盖了什么您正在寻找。我见过并使用过自己的最佳方法是在gsp / html中使用隐藏字段，并从客户端的javascript中检索这些值。

Would like to pass directly from the controller to a JavaScript file.

TestControler.groovy

def list() {
    render (view: "list", model:[theId: theId])
}

Test.js

function test() {
   // do smth with theId
}

Found solution have the rendered gsp in the middle, i.e. this one, but I would like to know if there is a way to avoid that including using hidden fields or having in the gsp file a javascript code snippet such as:

<g:javascript>
   function test(${theId}) {
       // do smth with theId
   }
</g:javascript>

解决方案

Unfortunately there does not seem to be anything that covers what you're looking for. The best approach that I have seen, and have used myself, is to use hidden fields in the gsp/html, and retrieve those values from javascript on the client side.
