我在加载脚本时遇到问题，这是我的 index.html 头：

<head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
    <title>Thai Express</title>
    <meta name="description" content="">
    <meta name="viewport" content="width=device-width">

    <link rel="stylesheet" href="css/normalize.css">
    <link rel="stylesheet" href="style.css">
    <script src="js/vendor/modernizr-2.6.2.min.js"></script>


    <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>

    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script>

    <link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css" rel="stylesheet" type="text/css"/>


    <script type="text/javascript" src="js/jQuery.fileinput.js"></script>

    <script type="text/javascript" src="js/thai-express.js"></script>

</head>

这是我得到的错误：

未捕获的类型错误：对象 [object Object] 没有方法“customFileInput”

这是文件“thai-express.js”开头的一个偷偷摸摸的地方，我在其中得到了错误：

    //on page load call _js_init
jQuery(document).ready(ThaiExpress_js_init);

function ThaiExpress_js_init(){
    jQuery(".cf_upload").customFileInput(); // custom upload field

    jQuery("#footer-promo li h3, ul#footer-promo li a.icon").hover(function(){ // hover both items simultaneously
        jQuery(this).parent().find("h3 a, a.icon").addClass("hover");
    },function(){   
        jQuery(this).parent().find("h3 a, a.icon").removeClass("hover");
    });

我试图更改脚本加载顺序，但找不到解决方案。

我想我找到了问题的根源。我使用 Firefox 对其进行了调试，发现它永远不会进入这个函数“jQuery.fn.customFileInput = function(){”但是，我不知道如何解决这个问题。这是“jQuery.fileinput.js”的内容。

jQuery.fn.customFileInput = function(){
return jQuery(this).each(function(){
//apply events and styles for file input element
var fileInput = jQuery(this)
    .addClass('customfile-input') //add class for CSS
    .mouseover(function(){ upload.addClass('customfile-hover'); })
    .mouseout(function(){ upload.removeClass('customfile-hover'); })
    .focus(function(){
        upload.addClass('customfile-focus'); 
        fileInput.data('val', fileInput.val());
    })
    .blur(function(){ 
        upload.removeClass('customfile-focus');
        jQuery(this).trigger('checkChange');
     })
     .bind('disable',function(){
        fileInput.attr('disabled',true);
        upload.addClass('customfile-disabled');
    })
    .bind('enable',function(){
        fileInput.removeAttr('disabled');
        upload.removeClass('customfile-disabled');
    })
    .bind('checkChange', function(){
        if(fileInput.val() && fileInput.val() != fileInput.data('val')){
            fileInput.trigger('change');
        }
    })
    .bind('change',function(){
        //get file name
        var fileName = jQuery(this).val().split(/\\/).pop();
        //get file extension
        var fileExt = 'customfile-ext-' + fileName.split('.').pop().toLowerCase();
        //update the feedback
        uploadFeedback
            .text(fileName) //set feedback text to filename
            .removeClass(uploadFeedback.data('fileExt') || '') //remove any existing file extension class
            .addClass(fileExt) //add file extension class
            .data('fileExt', fileExt) //store file extension for class removal on next change
            .addClass('customfile-feedback-populated'); //add class to show populated state
        //change text of button 
        uploadButton.text('Change');    
    })
    .click(function(){ //for IE and Opera, make sure change fires after choosing a file, using an async callback
        fileInput.data('val', fileInput.val());
        setTimeout(function(){
            fileInput.trigger('checkChange');
        },100);
    });

//create custom control container
var upload = jQuery('<div class="customfile"></div>');
//create custom control button
var uploadButton = jQuery('<span class="customfile-button" aria-hidden="true">Browse</span>').appendTo(upload);
//create custom control feedback
var uploadFeedback = jQuery('<span class="customfile-feedback" aria-hidden="true">No file selected...</span>').appendTo(upload);

//match disabled state
if(fileInput.is('[disabled]')){
    fileInput.trigger('disable');
}


//on mousemove, keep file input under the cursor to steal click
upload.insertAfter(fileInput); //insert after the input

fileInput.appendTo(upload);

});

};

谢谢
