Javascript 从下拉列表中选择时更改2个值

这是我的表格，我需要做的是

当用户选择“

Eyes

”时，“

lm_键

”和“

lm_表单

”字段将获得“5750”和“

cc0ce4fe280e46e986e5716f9feedaab

”值

当用户选择“

Ears

”时，“lm_键”和“

lm_表单

”字段将获得“5455”和“

b50ec1fe282a46e986efd8795aedcec

”值

眼睛
耳朵

为了在选择时一次更改2个值，我需要添加哪种jaavscript

谢谢

更改foobar，无论它是什么，您都可以这样做：（纯javascript，多变量用于了解发生了什么）

简短版本：

var values = ['', 5750, 5455]; // first key is 0
var keys = ['', 'cc0ce4fe280e46e986e5716f9feedaab', 'b50ec1fe282a46e986efd8795aedcec']; // first key is 0
function changeValues(){
    document.forms['form'].lm_form.value = values[document.forms['form'].selectField.value];
    document.forms['form'].lm_key.value = keys[document.forms['form'].selectField.value];
}

还发布了

changeValues

函数。我一直得到未捕获的类型错误：无法读取未定义的adamayated.html:46 changeValues adamayated.html:46 onchange的属性“target”

    funchition changeValues ( e ) {

Im_key = document.getElementsByName('Im_key')[0];
Im_form = document.getElementsByName('Im_form')[0];

if( e.target.value == 1 ) {

Im_key.value = 'foobar1';
Im_form.value = 'foobar2'


} else if( e.target.value == 1 ) {

Im_key.value = 'foobar3';
Im_form.value = 'foobar4'

}

}

function changeValues(){
    var values = ['', 5750, 5455]; // first key is 0
    var keys = ['', 'cc0ce4fe280e46e986e5716f9feedaab', 'b50ec1fe282a46e986efd8795aedcec']; // first key is 0
    var myform = document.forms['form'];
    var lm_form = myform.lm_form;
    var lm_key = myform.lm_key;
    var selected = myform.selectField.value;
    myform.lm_form.value = values[selected];
    myform.lm_key.value = keys[selected];
}

var values = ['', 5750, 5455]; // first key is 0
var keys = ['', 'cc0ce4fe280e46e986e5716f9feedaab', 'b50ec1fe282a46e986efd8795aedcec']; // first key is 0
function changeValues(){
    document.forms['form'].lm_form.value = values[document.forms['form'].selectField.value];
    document.forms['form'].lm_key.value = keys[document.forms['form'].selectField.value];
