Question

这是我的JS文件

window.$ = window.jQuery = WLJQ;
function wlCommonInit() {

}
$(document).ready(function(){

    $("#search").click(function(){
    GetMedicine();

    });



});
window.e='';
var univ;
function GetMedicine() {

    var medicine= $("#medicine").val();
    var location=$("#location").val();
    alert(medicine);
    var invocationData = {
        adapter : 'ATM',
        procedure : 'getMedicineDetails1',
        parameters: [medicine,location]
    };

    WL.Client.invokeProcedure(invocationData,{
        onSuccess : loadFeedsSuccess,
        onFailure : loadFeedsFailure
    });



}
function loadFeedsSuccess(result){

    window.e=result;
    univ=result.invocationResult.resultSet.length;
    WL.Logger.debug("loadsfeedssuccess");
 if (result.invocationResult.resultSet.length>0) 
    {

         var invocationData={
                    adapter : 'ATM',
                    procedure : 'checkCount',
                    parameters: []
            };
         WL.Client.invokeProcedure(invocationData,{onSuccess:countgreater});

         }
     else 
        {
        loadFeedsFailure1();

        }
}
function countgreater(result){

    if(result.invocationResult.resultSet.length>0)
        {

        alert("entered count greater");
        var c=result.invocationResult.resultSet[0].num;
        if(c>=0)
            {
    invocationData={
            adapter : 'ATM',
            procedure : 'getStoreDetails',
            parameters: [e[c].RegNo]
    };

            }

我希望通过将后果函数分配给全局变量“e”，将返回的resultSet分配给loadFeedsuccess。我无法这样做。当我在countgreater函数中读取e [c] .RegNo时，它显示错误无法从undefined中读取RegNo。有办法吗？

Answer 1

也许替换：

e[c].RegNo

使用：

e.invocationResult.resultSet[c].RegNo

如果这不起作用，只需添加日志语句，找出所需值的正确路径。例如：

alert(JSON.stringify(e))

或

console.log(JSON.stringify(e))

或

WL.Logger.debug(JSON.stringify(e))

在loadFeedsSuccess和countgreater个函数中。
