ここに選択ボックスがあります(私は使用して変更しました)。選択ボックスをクリックすると、テキスト入力に変わり、I ビームが表示されます。この I ビームを無効にしたかっただけです。どうすればそれを手に入れることができますか?

html は次のとおりです。

<select name="Items" id="Items">
    <option value="option1">option1</option>
    <option value="option2">option2</option>
    <option value="option3">option3</option>
    <option value="option4">option4</option>    
</select>

およびJquery:

$(document).ready(function () {
    $('#Items').selectbox();
});

jQuery.fn.extend({
    selectbox: function (options) {
        return this.each(function () {
            new jQuery.SelectBox(this, options);
        });
    }
});


if (!window.console) {
    var console = {
        log: function (msg) {}
    }
}

jQuery.SelectBox = function (selectobj, options) {

    var opt = options || {};
    opt.inputClass = opt.inputClass || "selectbox";
    opt.containerClass = opt.containerClass || "selectbox-wrapper";
    opt.hoverClass = opt.hoverClass || "current";
    opt.currentClass = opt.selectedClass || "selected"
    opt.debug = opt.debug || false;

    var elm_id = selectobj.id;
    var active = -1;
    var inFocus = false;
    var hasfocus = 0;
    //jquery object for select element
    var $select = $(selectobj);
    // jquery container object
    var $container = setupContainer(opt);
    //jquery input object 
    var $input = setupInput(opt);
    // hide select and append newly created elements
    $select.hide().before($input).before($container);


    init();

    $input.click(function () {
        if (!inFocus) {
            $container.toggle();
        }
    })
        .focus(function () {
        if ($container.not(':visible')) {
            inFocus = true;
            $container.show();
        }
    })
        .keydown(function (event) {
        switch (event.keyCode) {
            case 38:
                // up
                event.preventDefault();
                moveSelect(-1);
                break;
            case 40:
                // down
                event.preventDefault();
                moveSelect(1);
                break;

            case 13:
                event.preventDefault();
                $('li.' + opt.hoverClass).trigger('click');
                break;
            case 27:
                hideMe();
                break;
        }
    })
        .blur(function () {

im assuming your trying to use this jquery plugin

the reason there is a "line"(aka. the textbox cursor) is because this function:

function setupInput(options) {
    ...
    $input.attr("type", "text");
    ...
}

returns a textbox.

not exactly sure what your trying to achieve, but since the plugins documentation does not require such a function, then you should try implement it without using a <input type="text"/>, maybe just return a <div/> and settings its value through jQuery?
