js给文本框赋值文本域语句如下：input type=test name=testName id=testIdjavascript赋值操作：script language=javascriptdocument.getElementByIdx_x(testId).value=hello;/script注意：value与innerHTML的区别上面的value也可以写成innerHTML有value属性的标签才能使用getElementById().value比如input type=text value= /像div12345/div这种没有value属性的标签就用getElementById().innerHTML下面应用到具体页面来展示js的这种功能：!DOCTYPE html PUBLIC -//W3C//DTD XHTML 1.0 Transitional//EN /TR/xhtml1/DTD/xhtml1-transitional.dtdhtml xmlns=/1999/xhtmlheadmeta http-equiv=Content-Type content=text/html; charset=gb2312 /title订阅时事通讯/titlescript language=javascript /*document.write(h1 欢迎订阅时事通讯/h2);document.write(请选择您要的时事通讯：); function whoOnFocus() { // 您选中了哪一时事通讯var who = ; // 您选中的那一时事通讯for(var j = 0; j document.SubscriptionNewsletters.newsletters.length; j++) { if(document.SubscriptionNewsletters.newsletters[j].checked == true) { // 如果某复选框被选中 document.SubscriptionNewsletters.getElementById(whoOnFocus).value = ; // 清空文本框里的值 who = document.SubscriptionNewsletters.newsletters[j].value; // 被选中复选框的值 document.SubscriptionNewsletters.getElementById(whoOnFocus).value = who + 接收焦点; } } }functiondispInfo() {var s = ;for(var i = 0; i document.SubscriptionNewsletters.newsletters.length; i++) { if(document.SubscriptionNewsletters.newsletters[i].checked == true) { // 如果某复选框被选中 s += document.SubscriptionNewsletters.newsletters[i].value + br /; // 显示您选过的时事通讯项目 } }document.write(以下是您订阅的时事通讯：br /);document.write(br / + s); } */functionwhoOnFocus(){var newsletters = document.getElementsByName(newsletters)var s = //alert(newsletters[0].checked)document.SubscriptionNewsletters.whoOnFocus.value = for (var i=0;inewsletters.length;i++ ){if (newsletters[i].checked==true){s = s + newsletters[i].value}}document.SubscriptionNewsletters.whoOnFocus.value = s}functiondispInfo(){var newsletters = document.getElementsByName(newsletters)var s = for (var i=0;inewsletters.length ;i++ ){if (newsletters[i].checked==true){s = s + n
