javascript-为什么只执行部分代码

Question

在下面的代码中，最初在页面加载时，执行完整块。但是在页面加载后，只有else条件被执行。为什么？

请在下面找到完整的代码。

unction verifyrequestArray(id) {
  console.log("in verifyrequestarray" + requestArray.length);
  var y = true;
  //requestArray=["1012-abc","2089-xyz","1012-abc"];
  var tempArr = [];
  //for removing duplicates in the array
  for (i = 0; i < requestArray.length; i++) {


    if (tempArr.indexOf(requestArray[i]) == -1) {
      tempArr.push(requestArray[i]);
    }
  }
  //alert(tempArr);

  //verify if the value already exists

  for (j = 0; j < tempArr.length; j++) {

    if (tempArr.hasOwnProperty(id)) {
      console.log("req id already present in array");
      break;
    } else {

      console.log("req id not present in array");
      return false;
    }
  }

}



function getStatusfromArray(id) {
  console.log("in get status");
  requestStatus = requestArray.hasOwnProperty(id);
  console.log("status for " + id + ":" + requestStatus);
  return requestStatus;
}

function setTooltip(currentTag, status) {
  console.log("in settooltip" + currentTag);
  currentTag.attr("title", status); //setting status a tooltip
}

function getStatusUsingAjax(requestValue, callback) {
  console.log("inside function getStatusUsingAjax");
  var currentStatus;
  GM_xmlhttpRequest({
    method: "GET",
    url: link,
    async: false,
    onload: function(response) {

      if ($(response.responseText).find("#P16_STATUS2").size() === 1) {
        currentStatus = $(response.responseText).find("#P16_STATUS2").text();
        console.log("Status is " + currentStatus);
      } else if ($(response.responseText).find("#P16_STATUS3").size() === 1) {
        currentStatus = $(response.responseText).find("#P16_STATUS3").val();
        console.log("Status is " + currentStatus);
      }


      var pusharr2 = [requestValue + "-" + currentStatus];
      requestArray.push(pusharr2);
      //console.log("Updated Array is "+requestArray);

      callback(currentStatus);

    }
  });



}

function loadStatus(x) {

  $('.a-IRR-table tr').each(function(i) {
    var val = $(this).find("td").eq(0).text();
    if ((val !== "-") && (val !== "")) {
      link = $(this).find("td").eq(0).find("a").attr("href");
      linkTag = $(this).find("td").eq(0).find("a");
      console.log("Link Tag is " + linkTag);
      console.log("val is " + val);
      var x = verifyrequestArray(val);
      console.log("x is " + x);
      if (verifyrequestArray(val)) {
        var updatedStatus = getStatusfromArray(val);
        setTooltip(linkTag, updatedStatus);
      } else {
        console.log("in else");
        //var updatedStatus2=getStatusUsingAjax(val);
        getStatusUsingAjax(val, function(updatedStatus2) {
          console.log("UpdatedStatus2 is " + updatedStatus2);
          console.log("Link Tag is " + linkTag);
          setTooltip(linkTag, updatedStatus2);
        });

        sleep(1.5 * 1000);

      }
    }
  });
