我希望有人可以帮助我 - 我肯定是一个Javascript新手。我主要关注前端网站开发,但客户问我是否可以根据用户输入在线显示一些“成本”选项。我能够在第一次通过时取得成功,但是一旦我必须根据选择值进行计算,事情就会停止工作。
这是我的第一个传递,它适用于我的客户并正确计算,因为只有一个单位:
<script type="text/javascript">
function calcform() {
with (document.form1)
{ result.value = +number1.value * .75+ +number3.value} /*Calculates Option 1 One Year Costs.*/
{ result2.value = +number1.value * .75+ +number3.value + +number3.value} /*Calculates Option 1 Two Years.*/
{ result3.value = +number1.value * .75}/*Calculates Option 1 Leasing Fees.*/
{ result4.value = +number1.value * .08}/*Calculates Option 2 Leasing Fees.*/
{ result5.value = +number1.value * .08 *12 +500}/*Calculates Option 2 One Year Costs.*/
{ result6.value = +number1.value * .08 *24 +500}/*Calculates Option 2 Two Years.*/
}
</script>
<table>
<form name="form1" action="">
<tr>
<h5>Prospective Owners Cost Calculator:</h5><br/>
<h4>Enter Your Anticipated Monthly Rent Here:<br/>
<input type="text" id="number1" value="" size="20" />
</h4><br/>
<input type="button" id="Calculate" value="Calculate" onclick="calcform()" />
<input type="reset" id="reset" value=" Clear "/>
</tr><br/>
<tr>
<td>
<h4>
<strong>Option 1</strong>
</h4><br/>
<h4>Leasing Fee (75% of one month's rent):<br />
<input type="text" id="result3" value="" size="40" />
</h4><br/>
<h4>Monthly Management Fee (Fixed $79 x 12 months):<br />
<input type="text" id="number3" value="948" size="40" />
</h4><br/>
<h4>Total First Year:<br />
<input type="text" id="result" value="" size="40" />

<input type="text" id="result2" value="" size="40" />
</h4><br/>
</td>
<br/><br/>

<br><br>

<td>
<h4>
<strong>Option 2</strong>
</h4><br/>
<h4>Leasing Fee ($500 fixed):<br />
<input type="text" id="number5" value="500" size="40" />
</h4><br/>
<h4>Monthly Management Fee (8% of Gross Rents):<br />
<input type="text" id="result4" value="" size="40" />

我正在尝试添加第二个表单,该表单将在不同的HTML页面上使用选择下拉列表来驱动其他计算,因此用户可以指示单元数,这将驱动不同的计算。告诉你 - 我是新手!非常感谢您的帮助!
<script type="text/javascript">
function calcform()
{
with (document.form1)
{ result1.value = +number1.value * .75}/*Calculates Option 1 Leasing Fees.*/
{ result2.value = +number3.value * +number2.value}/*Calculates Option 1 Mgmt Fees all units.*/
}
</script>
<table><form name="form1" action="">
<tr><h5>Prospective Owners Cost Calculator:</h5><br/>
<h4>Enter Your Anticipated Monthly Rent Here (Total for all units):<br/>
<input type="text" id="number1" value="" size="20" /></h4><br/>
<h4>Enter the number of units (from 2-6)<br/>
<input type="number" name="number2" value="2" min="2" max="6"/></h4><br/>
<input type="button" id="Calculate" value="Calculate"

您可以在dev1.beastlyweb.com上看到此信息。我还在那里上传了Excel电子表格,其中包含客户希望在线复制的计算。
答案 0 :(得分:0)
看起来计算失败了,因为您将name="number2"
放入“输入单位数(2-6)”而不是id="number2"
的输入中。您在计算中id
正在调用该字段+number2.value
。
