grails远程功能：无法访问参数

Question

I've got a remoteFunction call in a javaScript function in my GSP file:

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)')}; 
    }

When I check the page source, the remotefunction creates this code:

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){}  } });; 

Why is my variable being replaced with 'null'?

Thanks!

Answer 1

试试这个作为remoteFunction调用中的params

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

Answer 2

Try this :

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