从change 3 dropdown values through javascript继续,只需要显示
function changeprice1(id){
选择第二个下拉列表,即Medical and Biomedical Manuscript Rewriting
。现在做什么,我现在开始思考了。 jS
中的任何帮助?
<script type="text/javascript">
function changeprice(id){
var value = id;
if(value == ""){
document.getElementById('price').value="";
alert("Please select one valid word count");
return false;
}
if(value == "Lessthan1000"){
var newprice = "USD 290";
}
if(value == "Lessthan2000"){
var newprice = "USD 540";
}
if(value == "Lessthan4000"){
var newprice = "USD 1050";
}
if(value == "Lessthan6000"){
var newprice = "USD 1900";
}
var eprice = newprice;
document.getElementById('price').value = eprice;
}
function changeprice1(id){
var value = id;
if(value == ""){
document.getElementById('price').value="";
alert("Please select one valid word count");
return false;
}
if(value == "ReLessthan1000"){
var newprice = "USD 390";
}
if(value == "ReLessthan2000"){
var newprice = "USD 690";
}
if(value == "ReLessthan4000"){
var newprice = "USD 1600";
}
if(value == "ReLessthan6000"){
var newprice = "USD 2900";
}
var eprice = newprice;
document.getElementById('price').value = eprice;
}</script>
这是第一个下拉列表
<select name="sp" id="sp" class="servicecategory">
<option value="" selected>Please Select...</option>
<option value="Medical and Biomedical Manuscript Writing" <?php if($servicename == "Medical and Biomedical Manuscript Writing"){ echo(" selected=\"selected\""); } ?>>Medical and Biomedical Manuscript Writing </option>
<option value="Medical and Biomedical Manuscript Rewriting" <?php if($servicename == "Medical and Biomedical Manuscript Rewriting"){ echo(" selected=\"selected\""); } ?>>Medical and Biomedical Manuscript Rewriting</option>
</select>
这是第二次下拉---
<select name="sp" id="sp" class="servicecategory" onChange="changeprice(this.value)">
<option value="" selected>Please Select...</option>
<option value="Lessthan1000">1 - 1000 words</option>
<option value="Lessthan2000">1001 - 2000 words</option>
<option value="Lessthan4000">2001 - 4000 words</option>
<option value="Lessthan6000">4001 - 6000 words</option>
</select>
这是价格显示的价格区域
<tr>
<td valign="top" align="right">Price:</td>
<td width="5"></td>
<td valign="top" align="left"><input type="text" name="price" id="price" value="" readonly="" size="20"><br />
</td>
</tr>
答案 0 :(得分:0)
试试这个
<script type="text/javascript">
function changeprice(id)
{
var value = id;
selectedmenu=document.getElementById("sp").value
if(selectedmenu == "select"){
alert("Please select one valid word count");
fnc();
return false;
}
if(selectedmenu=='Medical and Biomedical Manuscript Writing')
if(value == "Lessthan1000"){
var newprice = "USD 290";
}
if(value == "Lessthan2000"){
var newprice = "USD 540";
}
if(value == "Lessthan4000"){
var newprice = "USD 1050";
}
if(value == "Lessthan6000"){
var newprice = "USD 1900";
}
var eprice = newprice;
document.getElementById('price').value = eprice;
if(selectedmenu=='Medical and Biomedical Manuscript Rewriting')
{
if(value == "Lessthan1000"){
var newprice = "USD 390";
}
if(value == "Lessthan2000"){
var newprice = "USD 690";
}
if(value == "Lessthan4000"){
var newprice = "USD 1600";
}
if(value == "Lessthan6000"){
var newprice = "USD 2900";
}
var eprice = newprice;
document.getElementById('price').value = eprice;
}
}
function fnc()
{
document.getElementById("select").selected=true;
}
</script>
<select name="sp" id="sp" class="servicecategory" onchange="fnc()">
<option value="select" selected>Please Select...</option>
<option value="Medical and Biomedical Manuscript Writing" >Medical and Biomedical Manuscript Writing</option>

</select>
<select name="Word_Count" id="Word_Count" onChange="changeprice(this.value)">
<option value="select" id="select">Please Select...</option>

<option value="Lessthan4000">2001 - 4000 words</option>
