本文介绍了如何使用noUiSlider加载输入和输出在2个值之间的多个滑块?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我被卡住了.我想用noUiSlider创建多个范围滑块.每个滑块必须处理到[0,100]的值； (最小值= 0，最大值= 100，).此外，我需要按处理程序进行值的输出和输入，并由用户输入.
I'm stuck.. I want to create multiple range sliders with noUiSlider. Each slider has to handle between to values [0,100]; (min=0, max=100,). Moreover i need a output and input of values by handler and entered by User.
在此处查看我当前的代码:
See my current code here:
function data ( element, key ) {
return element.getAttribute('data-' + key);
}
var connectSlider = document.getElementsByClassName('slider');
var input0 = document.getElementsByClassName('input-format-0');
var input1 = document.getElementsByClassName('input-format-1');
var inputs = [input0, input1];
function createSlider ( slider ) {
noUiSlider.create( connectSlider,{
start: [0, 100],
connect: false,
step: Number(data(slider, 'step')) || 1,
range: {
'min': [0],
'max': [100],
},
tooltips: true,
connect: true,
format: {
to: function (value) {
return value + '%';
},
from: function (value) {
return value.replace('%', '');
},
}
});
}
connectSlider.noUiSlider.on('update', function( values, handle ) {
inputs[handle].value = values[handle];
});
Array.prototype.forEach.call(document.querySelectorAll('.slider'), createSlider);
function setSliderHandle(i, value) {
var r = [null,null];
r[i] = value;
connectSlider.noUiSlider.set(r);
}
// Listen to keydown events on the input field.
inputs.forEach(function(input, handle) {
input.addEventListener('change', function(){
setSliderHandle(handle, this.value);
});
input.addEventListener('keydown', function( e ) {
var values = connectSlider.noUiSlider.get();
var value = Number(values[handle]);
// [[handle0_down, handle0_up], [handle1_down, handle1_up]]
var steps = connectSlider.noUiSlider.steps();
// [down, up]
var step = steps[handle];
var position;
// 13 is enter,
// 38 is key up,
// 40 is key down.
switch ( e.which ) {
case 13:
setSliderHandle(handle, this.value);
break;
case 38:
// Get step to go increase slider value (up)
position = step[1];
// false = no step is set
if ( position === false ) {
position = 1;
}
// null = edge of slider
if ( position !== null ) {
setSliderHandle(handle, value + position);
}
break;
case 40:
position = step[0];
if ( position === false ) {
position = 1;
}
if ( position !== null ) {
setSliderHandle(handle, value - position);
}
break;
}
});
});
