如何在没有这么多重复代码的情况下更改自动完成'数据'参数？

Question

我正在尝试在data参数中为自动填充发送不同的值，具体取决于之前设置的全局变量lookupType。

但是，即使只有data部分，所有其他代码也会重复。

如何减少冗余代码？

在一个案例中，data部分是：

    data: {
        type: "full",
        location: "local",
        name: request.term
    },

而另一个则是这样的：

    data: {
        append: "no",
        doPreprocess: true,
        name: request.term,
        maxResults: 1000
    },

完整代码如下：

    $( "#lookup" ).autocomplete({
    if($("#hiddenLookupType").val() == "order")
    {

        source: function( request, response ) {
            $.ajax({
                url: lookupUrl,
                dataType: "jsonp",
                data: {
                    type: "full",
                    location: "local",
                    name: request.term
                },
                success: function( data ) {
                // do something
                    }));
                }
            });
        },
        minLength: 2,
        select: function( event, ui ) {
            log( ui.item ?
                "Selected: " + ui.item.label :
                "Nothing selected, input was " + this.value);
        },
        open: function() {
            $( this ).removeClass( "ui-corner-all" ).addClass( "ui-corner-top" );
        },
        close: function() {
            $( this ).removeClass( "ui-corner-top" ).addClass( "ui-corner-all" );
        }
    }
    else if($("#hiddenLookupType").val() == "inventory")
    {

        source: function( request, response ) {
            $.ajax({
                url: lookupUrl,
                dataType: "jsonp",
                data: {
                    append: "no",
                    doPreprocess: true,
                    name: request.term,
                    maxResults: 1000
                },
                success: function( data ) {
                // do something
                    }));
                }
            });
        },
        minLength: 2,
        select: function( event, ui ) {
            log( ui.item ?
                "Selected: " + ui.item.label :
                "Nothing selected, input was " + this.value);
        },
        open: function() {
            $( this ).removeClass( "ui-corner-all" ).addClass( "ui-corner-top" );
        },
        close: function() {
            $( this ).removeClass( "ui-corner-top" ).addClass( "ui-corner-all" );
        }
    }
});

Answer 1

而不是：

 data: {
                    type: "full",
                    location: "local",
                    name: request.term
                },

有：

data: GetData(this),


 function GetData(el)
 {
    ..Logic Here
 }

//calling it:
var parameters =    {
        type: "full",
        location: "local",
        name: request.term
    }

test(parameters);

//the method
function test(dataList){ 
 $( "#lookup" ).autocomplete({
    if($("#hiddenLookupType").val() == "order")
