grails遠程功能：無法訪問參數

Question

我的GSP文件中的javaScript函數中有一個remoteFunction調用：

function fnCreateEntitiesPerForceChart() {
      var interval = $("#entitiesPerForceTimeIntervalSelect").val();
      interval = escape(interval);
      var url = '${createLink(controller: 'federation', action: 'createEntitiesPerForceChart')}?interval='+interval;
      $("#entitiesPerForceChart").attr("src", url);
alert("interval is: " + interval);
      ${remoteFunction(controller: 'federation', 
        action: 'getEntitiesPerForceTable', 
        params: '\'interval\''+':'+interval, 
        onSuccess: 'fnUpdateEntitiesPerForceTable(data,textStatus)')}; 
    }

當我檢查頁面源代碼時，遠程功能將創建以下代碼：

try{DojoGrailsSpinner.show();}catch(e){} dojo.xhr('Get',{content:{'interval':null}, preventCache:true, url:'/FederationReporter/federation/getEntitiesPerForceTable', load:function(response){  fnUpdateEntitiesPerForceTable(data,textStatus); }, handle:function(response,ioargs){try{DojoGrailsSpinner.hide();}catch(e){} }, error:function(error,ioargs){try{DojoGrailsSpinner.hide();}catch(e){}  } });; 

為什么將我的變量替換為'null'？

謝謝！

Answer 1

試試這個作為remoteFunction調用中的params

params: '\\'interval\\': + interval'

Answer 2

嘗試這個 ：

function fnCreateEntitiesPerForceChart() {
  var interval = dojo.byId("entitiesPerForceTimeIntervalSelect").get("value");
  // [...] rest of your code
}
