1、在checkbox加上同样的name属性
2、直接上代码：function Lond_c氯短赤亻keck(objname){ obj = document.getEleme荏鱿胫协ntsByName(objname); checkval = []; for(k in obj){ if(obj[k].checked) checkval.push(obj[k].value); } return checkval; }
3、使用方法
4、效果
5、HTML代码<!DOCTYPE html><html><head> <title></title><script type="text/javascript" src='js/Lond.js'></script></head><body><input type="checkbox" name="hell" value="选中1"><input type="checkbox" name="hell" value="选中2"><input type="checkbox" name="hell" value="选中3"><input type="checkbox" name="hell" value="选中4"><button onclick="fun()">测试</button><script type="text/javascript">function fun(){alert(Lond_ckeck('hell'))//id)}</script></body></html>
6、如果上面出错请复制下面HTML代码：H哌囿亡噱TML代码<!DOCTYPE html><html><head> <title></title></head><body><input type="checkbox" name="hell" value="选中1"><input type="checkbox" name="hell" value="选中2"><input type="checkbox" name="hell" value="选中3"><input type="checkbox" name="hell" value="选中4"><button onclick="fun()">测试</button><script type="text/javascript">function fun(){alert(Lond_ckeck('hell'))//id)}function Lond_ckeck(objname){ obj = document.getElementsByName(objname); checkval = []; for(k in obj){ if(obj[k].checked) checkval.push(obj[k].value); } return checkval;}</script></body></html>
7、注意事项： 传入参数一定是name属性
