我正在尝试计算单选按钮和复选框的值.我有单选按钮按要求工作,但无法为复选框获取正确的脚本.我希望复选框有一个小计(工作正常),然后将该小计添加到单选按钮的计算中.以下是我到目前为止所拥有的.任何建议,将不胜感激.谢谢.
I am trying to calculate the values of radio buttons and checkboxes. I have the radio buttons working as required but cannot get the script right for the checkboxes. I want the check boxes to have a sub total (which is working fine) and then have that subtotal added to the calculation of the radio buttons. Below is what I have so far. Any suggestions would be appreciated. Thanks.
<form name="form1" id="form1" runat="server">
<legend>Header 1</legend>
<p><input id="rdo_1" type="radio" value="3" name="price" onClick="DisplayPrice(this.value);"><label for="radio1">Radio 1</label></p>
<p><input id="rdo_2" type="radio" value="2" name="price" onClick="DisplayPrice(this.value);"><label for="radio2">Radio 2</label></p>
<p><input id="rdo_2" type="radio" value="1" name="price" onClick="DisplayPrice(this.value);"><label for="radio3">Radio 3</label></p>

在Javascript中,如果有一个特定名称的texbox,那么length函数将返回undefined
.
In Javascript if there is single texbox of a specific name then length function will be return undefined
.
在这里你可以做两件事.
Here you can do two things.
第一个小计只有一个字段,因此您可以直接将值分配给val4,如下所示
val4 = document.form4.price4.value;
第二个如果要运行for循环那么
var val4 = 0;
var form4 = document.form4.getElementsByTagName('input');
for( i = 0; i < form4.length; i++ ){
if(form4[i].type == 'text' && form4[i].name == 'price4'){
if(isNaN(parseInt(form4[i].value)) == false){
val4 = parseInt(parseInt(val4) + parseInt(form4[i].value));
}
}
}
编辑
在函数中
<script language="JavaScript" type="text/javascript">
var total = document.getElementById("price4")
function clickCh(caller){
if(caller.checked){
add(caller)
} else {
subtract(caller)
}
finalResult();
}
function add(caller){ total.value = total.value*1 + caller.value*1}
function subtract(caller){ total.value = total.value*1 - caller.value*1}
function finalResult(){
var val1 = 0;
for( i = 0; i < document.form1.price.length; i++ ){
if( document.form1.price[i].checked == true ){
val1 = document.form1.price[i].value;
}
}
var val2 = 0;
for( i = 0; i < document.form2.price2.length; i++ ){
if( document.form2.price2[i].checked == true ){
val2 = document.form2.price2[i].value;
}
}
var val3 = 0;
for( i = 0; i < document.form3.price3.length; i++ ){
if( document.form3.price3[i].checked == true ){
val3 = document.form3.price3[i].value;
}
}
var val4 = 0;
var form4 = document.form4.getElementsByTagName('input');
for( i = 0; i < form4.length; i++ ){
if(form4[i].type == 'text' && form4[i].name == 'price4'){
if(isNaN(parseInt(form4[i].value)) == false){
val4 = parseInt(parseInt(val4) + parseInt(form4[i].value));
}
}
}
var sum=parseInt(val1) + parseInt(val2) + parseInt(val3) + parseInt(val4);
document.getElementById('valueTotal').value=sum;
}
</script>
