我不知道为什么当一个复选框被点击时,它会加倍相关的标签文本。有人可以帮我吗?
// add multiple select / deselect functionality
$("#selectall").click(function () {
$('.child').attr('checked', this.checked);
$('.ck,.chkbox,.checkAll ,input:radio').DcustomInput();
});
jQuery.fn.DcustomInput = function(){
$(this).each(function(i){
if($(this).is('[type=checkbox],[type=radio]')){
var input = $(this);
var id=input.attr('id');
// get the associated label using the input's id
var forlabel = $('label[for='+input.attr('id')+']');
var chklabel = forlabel.text();
forlabel.hide();
var label = $("<label for='"+id+"' class='checker'>"+chklabel+"</label>");
//get type, for classname suffix
var inputType = (input.is('[type=checkbox]')) ? 'checkbox' : 'radio';
// alert(label);
// wrap the input + label in a div
$('<div class="custom-'+ inputType +'"></div>').insertBefore(input).append(input, label);
// find all inputs in this set using the shared name attribute
if(input.is(':disabled')){
if(inputType == 'checkbox' && input.is(':checked')){
label.addClass(' checkedDisabled ');
} else{
label.addClass(' disabled ');
}
}
// necessary for browsers that don't support the :hover pseudo class on labels
label.hover(
function(){
if(!input.is(':disabled') ){
$(this).addClass('hover');
}
if(inputType == 'checkbox' && input.is(':checked') && !input.is(':disabled')){
$(this).addClass('checkedHover');
}
},
function(){ $(this).removeClass('hover checkedHover focus'); }
);
//bind custom event, trigger it, bind click,focus,blur events
input.bind('updateState', function(){
if (input.is(':checked') && !input.is(':disabled')) {
if (input.is(':radio')) {
var allInputs = $('input[name='+input.attr('name')+']');
allInputs.each(function(){
$('label[for='+$(this).attr('id')+']').removeClass('checked');
});
};
label.addClass('checked ');
}
else { label.removeClass('checked checkedHover checkedFocus '); }
})
.trigger('updateState')
.click(function(){
$(this).trigger('updateState');
})
.focus(function(){
label.addClass('focus');
if(inputType == 'checkbox' && input.is(':checked')){
$(this).addClass('checkedFocus');
}
})
.blur(function(){ label.removeClass('focus checkedFocus'); });
}
});
};
