为什么我的滑块工具提示在开始时不显示文本?

Question

我有三个滑块：

<div class="container">
<div class="row" id="time" >
<div class="col-xs-4">
Days: <b>1</b> <input id="days" type="text" class="span2" value="" data-slider-min="1" data-slider-max="31" data-slider-step="1" data-slider-value="[0,31]"/> <b>31</b>
</div>
<div class="col-xs-4">
Months: <b>January</b> <input id="months" type="text" data-provide="slider" data-slider-step="1" data-slider-min="0" data-slider-max="11" data-slider-tooltip="show" data-slider-value="[0,12]" /> <b>December</b>
</div>
<div class="col-xs-4">
Years: <b>0</b> <input id="years" type="text" class="span2" value="" data-slider-min="0" data-slider-max="2017" data-slider-step="1" data-slider-value="[0,2017]"/> <b>Today</b>
</div>
</div>
</div>

我使用以下js(请注意，它做了很多事情，但我们只在寻找days和years的工具提示问题(。

var months = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];
$("#days, #years").slider({
tooltip: 'always',
}); 
$("#days").slider({
formatter: function(value) {
return 'Days: ' + value;
}
});
$("#years").slider({
formatter: function(value) {
return 'Years: ' + value;
}
});
$("#months").slider({
tooltip: 'always',
value: [0, 12],
tooltip: 'always',
formatter: function(value) {
return months[value[0]] + " : " + months[value[1]];
},
});
$("input").on("slide", function(slideEvt) {
getData();
});
getData = function() {
var data = [];
for (var i = 0; i < 2; i++) {
data.push({
day: $('#days').slider().val().split(',')[i], 
month: months[$('#months').slider().val().split(',')[i]-1],
year: $('#years').slider().val().split(',')[i], 
}) ;
}  
console.log(data);
}

在滑块天数和年份的范围编号之前，它应该显示(示例(Days: 22:16和Years 1200:1985但标签Days和Years仅在我们开始与滑块交互后出现，而不是在我们加载它时一开始

好的，在检查滑块的未缩小源代码后，看起来需要额外的"刷新"调用，因为在初始化阶段没有调用格式化程序。只需像这样称呼relayout：

$("#days").slider({
formatter: function(value) {
return 'Days: ' + (value instanceof Array ? value.join(':'): value);
}
}).slider('relayout');
$("#years").slider({
formatter: function(value) {
return 'Years: ' + (value instanceof Array ? value.join(':'): value);
}
}).slider('relayout');

初始化两次时会发生此问题。

删除此

$("#days, #years").slider({
tooltip: 'always',
}); 
$("#days").slider({
formatter: function(value) {
return 'Days: ' + value;
}
});
$("#years").slider({
formatter: function(value) {
return 'Years: ' + value;
}
});

替换为此

$("#days").slider({
tooltip: 'always',
formatter: function(value) {
return 'Days: ' + value; //return ('Days: ' + value).replace(",", ":");
}
});
$("#years").slider({
tooltip: 'always',
formatter: function(value) {
return 'Years: ' + value; //return ('Years: ' + value).replace(",", ":");
}
});
