我做了用于移动范围按钮的代码,该值将增加跨度ID的值,我也通过JavaScript做到了这一点,但是我尝试在输入字段中获得相同的值,我不明白问题是什么请帮助我解决此问题。
var output = document.getElementById("demo");
document.getElementById("demo").value = output;
output.innerHTML = slider.value;
slider.oninput = function() {
output3.innerHTML = this.value;
output.innerHTML = this.value;
output2.innerHTML = this.value;
}
<div class="col-md-12">
<p>Loan Amount<span id="demo3"></span></p>
<input type="range" min="5000" max="50000" value="1000" class="slider" id="myRange" step="1000">
</div>
<div class="col-md-12">
<p>Loan Period</p>
<input type="range" min="10" max="50" class="slider" id="myRange2" step="10" oninput="getInput(this.value)">
</div>
<div class="col-md-4">
<img src="./assets/img/cal-01.png" style=" max-width: 48%; " />
<p>Loan Amount:<br/><span id="demo"></span></p>
</div>
<div class="col-md-4">
<img src="./assets/img/cal-02.png" style=" max-width: 37%; " />
<p>Loan Period:<br/><span id="demo4"></span> Days</p>
</div>
<input type="text" class="form-control" id="demo" name="demo">
我想将跨度ID值传递给输入字段ID
答案 0 :(得分:1)
首先,在html文档中,没有两个元素应该具有相同的ID,因此您必须将ID为“ demo”的元素之一更改为唯一。
然后使用.textContent
获取span元素上的内容。
var output = document.getElementById("span-demo"); // this is the span element
document.getElementById("demo").value = output.textContent; // put the text context inside the value of the input element.
output.innerHTML = slider.value;
slider.oninput = function() {
output3.innerHTML = this.value;
output.innerHTML = this.value;
output2.innerHTML = this.value;
}
