Рабочие примеры:
В дальнейшем я должен отметить 2 основных изменения. Я добавил CSS, чтобы сделать то, что вы пытались сделать с метками в «коде» (там, где это действительно не место).
Кроме того, я изменил HTML для «простоты использования jQuery». Тем не менее, я все же отметил в комментариях, как вы можете легко изменить его обратно.
HTML
<center>
<button>Create New CheckBox</button>
</center>
<hr />
<div id="CheckBoxes">
<input class="inp-checkbox" />
<input class="inp-checkbox" />
<input class="inp-checkbox" />
<input class="inp-checkbox" />
</div>
CSS
.inp-checkbox+label {
width:16px;
height:16px;
vertical-align:middle;
}
JavaScript/jQuery
// keep in mind, and i will explain, some of these "moving-parts" or not needed, but are added to show you the "ease" of jquery and help you see the solution
// This global function is designed simply to allow the creation of new checkboxes as you specified, however, if you won't be making check boxes at end user time, then i suggest simply moving it to within the .each statement found later on.
// Also, this could easily be written as a jQuery plugin so that you could make a "chainable" one-line call to change checkboxes to this but let's get to the nitty gritty first
function createCheckBox(ele, i) {
// First I simply create the new ID here, of course you can do this inline, but this gives us a bottleneck for possible errors
var newID = "cbx-"+i;
// below we use the param "ele" wich will be a jQuery Element object like $("#eleID")
// This gives us the "chainability" we want so we don't need to waste time writing more lines to recall our element
// You will also notice, the first thing i do is asign the "attribute" ID
ele.attr({ "id": newID })
// Here we see "chainability at work, by not closing the last line, we can move right on to the next bit of code to apply to our element
// In this case, I'm changing a "property", keep in mind this is kinda new to jQuery,
// In older versions, you would have used .attr but now jQuery distinguishes between "attributes" and "properties" on elements (note we are using "edge", aka. the latest jQuery version
.prop({ "type": "checkbox" })
// .after allows us to add an element after, but maintain our chainability so that we can continue to work on the input
// here of course, I create a NEW label and then immidiatly add its "for" attribute to relate to our input ID
.after($("<label />").attr({ for: newID }))
// I should note, by changing your CSS and/or changing input to <button>, you can ELIMINATE the previous step all together
// Now that the new label is added, lets set our input to be a button,
.button({ text: false }) // of course, icon only
// finally, let's add that click function and move on!
// again, notice jQuery's chainability allows us no need to recall our element
.click(function(e) {
// FYI, there are about a dozen ways to achieve this, but for now, I'll stick with your example as it's not far from correct
var toConsole = $(this).button("option", {
icons: {
primary: $(this)[0].checked ? "ui-icon-check" : ""
}
});
console.log(toConsole, toConsole[0].checked);
});
// Finally, for sake of consoling this new button creation and showing you how it works, I'll return our ORIGINAL (yet now changed) element
return ele;
}
$(function() {
// This .each call upon the inputs containing the class I asiged them in the html,
// Allows an easy way to edit each input and maintain a counter variable
// Thus the "i" parameter
// You could also use your ORIGINAL HTML, just change $(".inp-checkbox") to $("input:[type='checkbox']") or even $("input:checkbox")
$(".inp-checkbox").each(function(i) {
// as previously noted, we asign this function to a variable in order to get the return and console log it for your future vision!
var newCheckBox = createCheckBox($(this), i);
console.log(newCheckBox);
});
// This next button added is simply to show how you can add new buttons at end-time
// ENJOY!!!
$("button").button().on("click", function(e) {
var checkBoxCount = $("#CheckBoxes .inp-checkbox").length;
var newCheckBox = $("<input />").addClass("inp-checkbox").appendTo($("#CheckBoxes"));
createCheckBox(newCheckBox , checkBoxCount);
console.log(newCheckBox);
});
});
Обновление: Первоначальная цель здесь заключалась в том, чтобы просто ответить на вопрос, который заключался в создании флажка в стиле пользовательского интерфейса jQuery и демонстрации того, как jQuery можно использовать несколькими способами. Однако в более позднем комментарии задавался вопрос, как включить в него метку традиционного стиля. Хотя для этого есть миллиард вариантов, я просто возьму из вышеперечисленного и дополню.
Первый вариант, который я выбрал, довольно прост. Используя jsFiddle (without comments with UI theme switcher!), я внес следующие изменения:
JavaScript/jQuery
// First I add a new variable.
// It will simply be for a new "wrapper" element, in which to ensure our button is encased.
// Giving this element a new class gives easy access for later CSS or Event Triggering of sub elements (like the checkbox)
var newID = "cbx-"+i,
wrapper = $('<div />', { 'class': 'ui-checkbox-wrapper' }).appendTo('#CheckBoxes');
// Then I added a line to our ele series of methods.
// This line simply append our element (checkbox) to our new wrapper
// Take Note at how I added this method at start rather than at end.
// Had I not done this, then the label would not have been wrapped!
ele.appendTo(wrapper) // <-- new line!
.attr({ "id": newID })
Затем я просто добавил следующий CSS:
#CheckBoxes .ui-button .ui-button-text {
background: #A9A9A9;
display: inline;
font-size: 16px;
left: 19px;
padding: 0;
position: relative;
text-indent: 0;
top: -4px;
}
Результаты!
