JSON对象中的Send函数(带参数)

function json javascript

首次触发 packtNs.graduateForm.loadEvent packtNs.common.populateWithTodaysDate("packt_supervisor", "packt_postgraduatestartdate") 函数到 packtNs.common.wireOnChangeEvents 功能。

这是我的密码:

var packtNs = packtNs || {};

packtNs.common = packtNs.common || {};

/**
* A method that populates the post graduate start date
* when the supervisor lookup is populated.
* @returns {Void}
*/

packtNs.common.populateWithTodaysDate = function(attributeToMonitor, dateAttributeToChange)
{
    console.log("Populatewithtodaysdate function triggered");
}

packtNs.common.wireOnChangeEvents =
    function(eventAttributeTuples){
        debugger;
        for (var i in eventAttributeTuples) {
           console.log(eventAttributeTuples[i].attribute);
           ////attribute is OK
           console.log(eventAttributeTuples[i].function);
           ////function is always undefined. eventAttributeTuples[0] object doesnt have function - tried different names
        }

}

packtNs.graduateForm = packtNs.graduateForm || {};

packtNs.graduateForm.loadEvent = function(){
    packtNs.common.wireOnChangeEvents([
        { 
            attribute: "packt_supervisor",
            function:packtNs.common.populateWithTodaysDate("packt_supervisor", "packt_postgraduatestartdate")
        }
    ]);
    debugger;
}

这是一个名称间隔的对象,不是JSON,但是要获得一些东西,必须返回一些东西。我把你的“功能”改名为“神话”,因为它错了。

var packtNs = packtNs || {};

packtNs.common = packtNs.common || {};

/**
 * A method that populates the post graduate start date
 * when the supervisor lookup is populated.
 * @returns {Void}
 */

packtNs.common.populateWithTodaysDate = function(attributeToMonitor, dateAttributeToChange) {
  console.log("Populatewithtodaysdate function triggered");
  return {
    arg1: attributeToMonitor,
    arg2: dateAttributeToChange
  };
}

packtNs.common
  .wireOnChangeEvents = function(eventAttributeTuples) {
    //debugger;
    console.log("tup:", eventAttributeTuples);
    for (var i in eventAttributeTuples) {
      console.log(eventAttributeTuples[i].attribute);
      ////attribute is OK
      console.log(eventAttributeTuples[i].mything);
      ////function is always undefined. eventAttributeTuples[0] object doesnt have function - tried different names
    }
    return eventAttributeTuples;
  }

packtNs.graduateForm = packtNs.graduateForm || {};

packtNs.graduateForm.loadEvent = function() {
  return packtNs.common.wireOnChangeEvents([{
    attribute: "packt_supervisor",
    mything: packtNs.common.populateWithTodaysDate("packt_supervisor", "packt_postgraduatestartdate")
  }]);
  // debugger;
}

var myresult = packtNs.graduateForm.loadEvent();
console.log("myresult:",myresult);

首先,正如在您的问题下面的注释中指出的,将属性名从“function”更改为其他名称。然后我建议您尝试将传递的字符串表示形式的函数调用到eval方法中(请参见: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/eval )
