Question

我需要将所选值或变量分配给新变量并转发到输入字段的函数。任何人都可以帮助我吗？ :>

function myFunction(){
    //function 
}
</script>

<input id="price-postfix1" onclick="myFunction()" name="price-postfix" type="radio" value="$option1"/>Option1<br>
<input id="price-postfix2" onclick="myFunction()" name="price-postfix" type="radio" value="$option2"/>Option1<br>
<input id="price-postfix3" onclick="myFunction()" name="price-postfix" type="radio" value="$option3"/>Option1<br>

<input id="price-postfix" name="price-postfix" type="text" readonly="readonly" value="$result"/>

Answer 1

使用this

将当前对象传递给函数myFunction

Live Demo

<input id="price-postfix1" onclick="myFunction(this)" name="price-postfix" type="radio" value="$option1"/>Option1<br>
<input id="price-postfix2" onclick="myFunction(this)" name="price-postfix" type="radio" value="$option2"/>Option1<br>
<input id="price-postfix3" onclick="myFunction(this)" name="price-postfix" type="radio" value="$option3"/>Option1<br>

function myFunction(obj){
    document.getElementById('price-postfix').value = obj.value;
}
