此代码中的所有内容都按照我的要求运行,除非我不知道如何将滑块上的任何数字应用于number
变量。你能给予的任何帮助我都会非常感激!
var range = document.querySelector('.inputRange');
var field = document.getElementById('num1');
range.addEventListener('input', function (e) {
field.value = e.target.value;
});
field.addEventListener('input', function (e) {
range.value = e.target.value;
});
var number = 2000;
document.getElementById("id").innerHTML = number.toLocaleString('en');
var number2 = number;
if (number2 >= 10000) {
number2 = Math.round(+number + 10);
}
else if (number2 >= 5000) {
number2 = Math.round(+number + 5);
}
else {
number2 = Math.round(+number + 1);
}
document.getElementById("id2").innerHTML = number2.toLocaleString('en');

<input class="inputRange" type="range" min="1000" max="50000" value="1000" step="1000" id="slider"/>
<input class="inputNumber" id="num1" min="0" max="100" type="number" value="1000" />
<p> <span id="id"></span></p>
<p>$<span id="id2"></span></p>

以下是工作代码:http://jsfiddle.net/e0s8z4hm/
基本上在range.addEventListener
中你没有更新#id2中的值。
当前:
range.addEventListener('input', function (e) {
field.value = e.target.value;
});
做到:
range.addEventListener('input', function(e) {
field.value = e.target.value;
。$( '#ID2')HTML(e.target.value); //添加此行
});
