这是一个选择框(我已经使用和修改过)。当我点击选择框时,它变成文本输入并显示工字梁。只是想禁用这个工字梁。我怎么能得到它?
这是html:
<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>
和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();
$('li.' + opt.hoverClass).trigger('click');
break;
case 27:
hideMe();
break;
}
})
.blur(function () {
if ($container.is(':visible') && hasfocus > 0) {
if (opt.debug) console.log('container visible and has focus')
} else {
hideMe();
}
});
function hideMe() {
hasfocus = 0;
$container.hide();
}
function init() {
$container.append(getSelectOptions($input.attr('id'))).hide();
var width = $input.css('width');
$container.width(width);
}
function setupContainer(options) {
var container = document.createElement("div");
$container = $(container);
$container.attr('id', elm_id + '_container');
$container.addClass(options.containerClass);
return $container;
}
function setupInput(options) {
var input = document.createElement("input");
var $input = $(input);
$input.attr("id", elm_id + "_input");
$input.attr("type", "text");
$input.addClass(options.inputClass);
$input.attr("autocomplete", "off");
$input.attr("readonly", "readonly");
$input.attr("tabIndex", $select.attr("tabindex"));
return $input;
}
function moveSelect(step) {
var lis = $("li", $container);
if (!lis) return;
active += step;
if (active < 0) {
active = 0;
} else if (active >= lis.size()) {
active = lis.size() - 1;
}
lis.removeClass(opt.hoverClass);
$(lis[active]).addClass(opt.hoverClass);
}
function setCurrent() {
var li = $("li." + opt.currentClass, $container).get(0);
var ar = ('' + li.id).split('_');
var el = ar[ar.length - 1];
$select.val(el);
$input.val($(li).html());
return true;
}
function getCurrentSelected() {
return $select.val();
}
function getCurrentValue() {
return $input.val();
}
function getSelectOptions(parentid) {
var select_options = new Array();
var ul = document.createElement('ul');
$select.children('option').each(function () {
var li = document.createElement('li');
li.setAttribute('id', parentid + '_' + $(this).val());
li.innerHTML = $(this).html();
if ($(this).is(':selected')) {
$input.val($(this).html());
$(li).addClass(opt.currentClass);
}
ul.appendChild(li);
$(li)
.mouseover(function (event) {
hasfocus = 1;
if (opt.debug) console.log('over on : ' + this.id);
jQuery(event.target, $container).addClass(opt.hoverClass);
})
.mouseout(function (event) {
hasfocus = -1;
if (opt.debug) console.log('out on : ' + this.id);
jQuery(event.target, $container).removeClass(opt.hoverClass);
})
.click(function (event) {
var fl = $('li.' + opt.hoverClass, $container).get(0);
if (opt.debug) console.log('click on :' + this.id);
$('li.' + opt.currentClass).removeClass(opt.currentClass);
$(this).addClass(opt.currentClass);
setCurrent();
hideMe();
});
});
return ul;
}
};
感谢。
答案 0 :(得分:1)
我假设您尝试使用this jquery plugin
存在“line”(又名文本框光标)的原因是因为这个函数:
function setupInput(options) {
...
$input.attr("type", "text");
...
}
返回一个文本框。
不完全确定您要实现的目标,但由于插件文档不需要这样的功能,因此您应该尝试在不使用<input type="text"/>
的情况下实现它,也许只需返回<div/>
和设置它通过jQuery的价值?
