php和Javascript调用更改单选按钮 [英] php and Javascript call to change radio button
问题描述
我正在尝试设置单选按钮的状态。我不明白我是做什么的？b $ b做错了。对不起，我是新来的..我需要另外一双眼睛来看看这段代码。我想用这个
代码链接设置单选按钮：
echo''SCRIPT语言= JavaScript
setCheckedValue （QUOT; ''。$ _ SESSION [ '' abbr_letter '']。 '' "）;< / SCRIPT> ''; //？
<代码片段>
<？php
session_start（）;
if（！isset（$ _ SESSION [''abbr_letter'']））{
$ _SESSION [''abbr_letter''] =''A'';
}
require_once''includes / config.inc.php'';
require_once''includes / header.inc.php'';
if（xdebug_is_enabled（））
echo" enable";
else
xdebug_enable（ ）;
//
//开始表格

< HTML>
< HEAD>
< link href =" quotesCss.css"的rel ="样式表" type =" text / css">
< SCRIPT TYPE =" text / javascript">
<！ -
//设置带有给定值的单选按钮作为检查
//如果没有单选按钮则不执行任何操作
//如果给定值不存在，所有单选按钮
//重置为未选中
函数setCheckedValue（newValue）{
var len = document.author_abbrv.abbr_letter。长度
for（var i = 0; i< len; i ++）
{
document.author_abbrv.abbr_letter [i] .checked = false;
if（document.author_abbrv.abbr_letter [i] .value ==
newValue.toString（））
{
document.author_abbrv.abbr_letter [i] .checked = true;
}
}
}
