ayuda para identificar variables Gracias de antemano por sus respuestas
quisiera una ayuda para identificar las variables que se puedan cambiar en este archivo js,
tengo un slider, pero quisiera tener otro con diferentes caracteristicas, pero cuando copio el codigo, me salen las caracteristicas del slider anterior, y bueno, intente cambiando algunas variables, pero tengo la idea de colocarlo en otro archivo js y cambiar las variables para poder trabajarlo por separado...
pero la verdad no me conosco todas las variables, metodos o propiedades del slider asi que recurro a su ayuda...
este es el codigo...
jQuery.fn.selectToUISlider = function(settings){
var selects = jQuery(this);
//accessible slider options
var options = jQuery.extend({
labels: 5, //number of visible labels
tooltip: true, //show tooltips, boolean
tooltipSrc: 'text',//accepts 'value' as well
labelSrc: 'value',//accepts 'value' as well ,
sliderOptions: null
}, settings);
//handle ID attrs - selects each need IDs for handles to find them
var handleIds = (function(){
var tempArr = [];
selects.each(function(){
tempArr.push('handle_'+jQuery(this).attr('id'));
});
return tempArr;
})();
//array of all option elements in select element (ignores optgroups)
var selectOptions = (function(){
var opts = [];
selects.eq(0).find('option').each(function(){
opts.push({
value: jQuery(this).attr('value'),
text: jQuery(this).text()
});
});
return opts;
})();
//array of opt groups if present
var groups = (function(){
if(selects.eq(0).find('optgroup').size()>0){
var groupedData = [];
selects.eq(0).find('optgroup').each(function(i){
groupedData[i] = {};
groupedData[i].label = jQuery(this).attr('label');
groupedData[i].options = [];
jQuery(this).find('option').each(function(){
groupedData[i].options.push({text: jQuery(this).text(), value: jQuery(this).attr('value')});
});
});
return groupedData;
}
else return null;
})();
//check if obj is array
function isArray(obj) {
return obj.constructor == Array;
}
//return tooltip text from option index
function ttText(optIndex){
return (options.tooltipSrc == 'text') ? selectOptions[optIndex].text : selectOptions[optIndex].value;
}
//plugin-generated slider options (can be overridden)
var sliderOptions = {
step: 1,
min: 0,
orientation: 'horizontal',
max: selectOptions.length-1,
range: selects.length > 1,//multiple select elements = true
slide: function(e, ui) {//slide function
var thisHandle = jQuery(ui.handle);
//handle feedback
var textval = ttText(ui.value);
thisHandle
.attr('aria-valuetext', textval)
.attr('aria-valuenow', ui.value)

//control original select menu
var currSelect = jQuery('#' + thisHandle.attr('id').split('handle_')[1]);
