Javascript 带有jQuery ui主题的自动样式复选框
(这里是jquerynoob) 我正在尝试编写一个脚本,当我编写Javascript 带有jQuery ui主题的自动样式复选框,javascript,jquery,jquery-ui,Javascript,Jquery,Jquery Ui,(这里是jquerynoob) 我正在尝试编写一个脚本,当我编写时,它会自动将其转换为jqueryui按钮,看起来像一个复选框。 到目前为止的示例代码 var newCheckboxID = 0; $( "input:checkbox" ).attr('id', "cbx-" + nextCheckboxID++); // how to do that? $( "input:checkbox" ).after("<lab
时,它会自动将其转换为jqueryui按钮,看起来像一个复选框。
到目前为止的示例代码
var newCheckboxID = 0;
$( "input:checkbox" ).attr('id', "cbx-" + nextCheckboxID++); // how to do that?
$( "input:checkbox" ).after("<label style='width:16px; height:16px; vertical-align:middle;'></label>");
$( "input:checkbox" ).next().attr("for", $(this).attr('id') ); // doesn't work for sure
$( "input:checkbox" ).button();
$( "input:checkbox" ).button( "option", "text", false );
$( "input:checkbox" ).attr("onclick", "$(this).button( 'option', 'icons', {primary:((this.checked)?'ui-icon-check':null),secondary:null} )");
var newCheckboxID=0;
$(“输入:复选框”).attr('id',“cbx-”+nextCheckboxID++);//怎么做?
$(“输入:复选框”)。在(“”)之后;
$(“输入:复选框”).next().attr(“for”,$(this.attr('id'));//肯定不行
$(“输入:复选框”).button();
$(“输入:复选框”)。按钮(“选项”,“文本”,false);
$(“输入:复选框”).attr(“onclick”,“this.”按钮('option','icons',{primary:((this.checked)?'ui-icon-check':null),secondary:null});
对不起,如果这太明显了,但我已经在这件事上浪费了一个多小时
编辑
最后用老式的方式完成了(因为没有工作部件)。
任何关于使其更紧凑和“更jQuery”的评论都将被推荐。。。
代码示例
// ---- set ids
var checkboxID = 0;
//$( "input:checkbox" ).attr('id', "cbx-" + nextCheckboxID++); // how to do that?
var cboxes = document.getElementsByTagName('input'); // <-- do this instead
for(var i=0; i<cboxes.length; i++){
if( cboxes[i].getAttribute('type')!='checkbox' ) continue;
cboxes[i].setAttribute('id', 'cbx-'+checkboxID++);}
// ---- add labels
$( "input:checkbox" ).after("<label style='width:16px; height:16px; vertical-align:middle;'></label>");
//$( "input:checkbox" ).next().attr("for", $(this).attr('id') ); // doesn't work this
for(var i=0; i<cboxes.length; i++){ // <-- do this instead
if( cboxes[i].getAttribute('type')!='checkbox' ) continue;
cboxes[i].nextSibling.setAttribute('for', cboxes[i].getAttribute('id') );}
// ---- create
$( "input:checkbox" ).button();
$( "input:checkbox" ).button( "option", "text", false );
$( "input:checkbox" ).attr("onclick", "$(this).button( 'option', 'icons', {primary:((this.checked)?'ui-icon-check':null),secondary:null} )");
/----设置ID
var checkboxID=0;
//$(“输入:复选框”).attr('id',“cbx-”+nextCheckboxID++);//怎么做?
var cboxes=document.getElementsByTagName('input');// 工作实例:
在下面,我应该注意到两个主要的变化。我添加了CSS来完成您试图对“代码”中的标签所做的工作(它实际上不属于这些标签)
另外,为了“易于jQuery”的使用,我修改了HTML。然而,我仍然在评论中指出,您可以轻松地将其更改回来
HTML
JavaScript/jQuery
然后我简单地添加了以下CSS:
#CheckBoxes .ui-button .ui-button-text {
background: #A9A9A9;
display: inline;
font-size: 16px;
left: 19px;
padding: 0;
position: relative;
text-indent: 0;
top: -4px;
}
这其实不是问题,只花了几分钟,我的大部分时间都花在了“玩”上:p,说到这里,我添加了另一个链接,在这里我展示了jQuery的更多用法,并用计时器“玩”了一圈,享受查看它的乐趣,祝未来的爱好者好运@阿波罗数字顺便说一句,欢迎来到StackOverflow,你会喜欢这里的@SpYk3HH-一段很棒的代码,唯一缺少的是作为插件的代码(这样可以更容易地创建checkbox$(“输入:checkbox”).checkbox();
或像这样简单的东西),甚至与jqueryUI:集成),谢谢分享!我对你的第一把小提琴做了一点改进,也许有人会觉得有用。我发现当选中这些样式化的复选框时(顺便说一句,非常棒),原始(请参阅:随表单提交)复选框的“选中”值没有改变。这里有一个新的修改:我已经修复了这个脚本,如果在创建过程中已经选中了复选框,那么它就不能正常工作。->
.inp-checkbox+label {
width:16px;
height:16px;
vertical-align:middle;
}
// 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);
});
});
// 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 })
