String[] picked = request.getParameterValues("open");
if (picked != null) {
for (int i = 0;i < picked.length; i++) {
// System.out.println("11"+picked[i]);
uDao.getCheckOpen( picked[i]);
}
} 今天怀着惶恐的心情用了下checkbox,一直以为挺神秘的东西,可是当你决定静下心来要把它搞定的时候,才发现事情远没有想象中困难O(∩_∩)O~
*****************************************************************************************************
从网上找的理论:
(获取checkbox中的值)String[] picked = request.getParameterValues("colname");
String[] a=new String[20];
if (picked != null) {
for (int i = 0;i < picked.length; i++) {
out.println(" "+picked[i]);
} else {
out.println ("none");
} 如何jsp页面checkbox实现全选.
用javascript吧。<html>
<body>
<script>
function kk(){
var handleEl = document.getElementById("kkHandler");
var els = document.getElementsByName("kk");
for(i=0;i<els.length;i++){
els[i].checked = handleEl.checked;
}
}
</script>
<input type=checkbox name="kkHandler">全选<br>
<input type=checkbox name="kk">
<input type=checkbox name="kk">
</body>
</html> 2:<form name="form" ID="Form1">
<input type="checkbox" name="id" value="" ID="Checkbox1">1
<input type="checkbox" name="id" value="" ID="Checkbox2">2
<input type="checkbox" name="chose" value="" ID="Checkbox5">allselect
</form>
<script>
function selectAll()
{
if(!document.form.id.length){
if(document.form.chose.checked){
document.form.id.checked=true;
}
else{
document.form.id.checked=false;
}
}
else{
for(var i=0;i<document.form.id.length;i++){
if(document.form.chose.checked){
document.form.id[i].checked=true;
}
else{
document.form.id[i].checked=false;
}
}
}
}
</script> ******************************************************************************************************
我的代码
jsp页面代码:<script LANGUAGE = "javaScript">
<!--
function selectAll()
{
if(!document.form.open.length){
if(document.form.chose.checked){
document.form.open.checked=true;
}
else{
document.form.open.checked=false;
}
}
else{
for(var i=0;i<document.form.open.length;i++){
if(document.form.chose.checked){
document.form.open[i].checked=true;
}
else{
document.form.open[i].checked=false;
}
}
}
}
-->
</script>
<logic:present name="Infor">
<logic:iterate id="show" name="Infor">
<tr bgcolor = '#E7F1FE'>
<td width="5%">
<logic:equal value="未开通" name="show" property="status">
<input type="checkbox" name="open" value="<bean:write name="show" property="legalPersonCode" />">
</logic:equal> action 里面的写法:
String[] picked = request.getParameterValues("open");
if (picked != null) {
for (int i = 0;i < picked.length; i++) {
// System.out.println("11"+picked);
uDao.getCheckOpen( picked);
}
}
