Look at the following two ways to implement: JS checkbox method One:
Copy CodeThe code is as follows: function Checkall () {var code_values = document.all[' Code_value '); if (code_values.length) {
for (Var i=0;i<code_values.length;i++) {code_values[i].checked = true;}} else{code_values.checked = True;}} function Uncheckall () {var code_values = document.all[' Code_value '];
if (code_values.length) {for (Var i=0;i<code_values.length;i++) {
code_values[i].checked = false; }}else{code_values.checked = false;}} function Multipledelete () {var num = 0; var code_values = document.all[' Code_value ']; if (code_values.length) {
for (Var i=0;i<code_values.length;i++) {if (code_values[i].checked = = true) {num + +;}}} else{if (code_values.checked = = true) {num + +;}} if (num = = 0) {alert (' Please select Delete item ');} if (num >0) {doc Ument. Bucodesearch.action = ' <%=eusutil.getpage ("lookup.generic.bucode.delete.s")%> ';
Document. Bucodesearch.submit (); }} </script>
JS checkbox Method Two:
Copy CodeThe code is as follows: function Checkall () {var code_values = document.getelementsbytagname ("input"); for (i = 0;i < code_values.length; i++) {if (Code_values[i].type = = "checkbox") {
Code_values[i].checked = true; }}} function Uncheckall ()
{var code_values = document.getelementsbytagname ("input"); for (i = 0;i < code_values.length;i++) {if (Code_values[i]. Type = = "checkbox")
{code_values[i].checked = false;} }} function Multipledelete () {if (document. bucodesearch.elements["Code_value"])
{var num = 0; var fm = document. Bucodesearch; if (document. bucodesearch.elements["Code_value"]) {var elm = document. bucodesearch.elements["Code_value"]; var ename = "Code_value";
if (elm.length) {var len = fm.elements[ename].length; for (var i = 0; i< len; i++) {var e = fm.elements[ename][i]; if (e.checked = = True) {num++;} }} else {if (elm.checked = = True) {
num++; }} if (num > 0) {
Document. Bucodesearch.action = ' <%=eusutil.getpage ("lookup.generic.bucode.delete.s")%> ';
Document. Bucodesearch.submit (); } } } }
Code_value is the name of the checkbox form and Bucodesearch is the form name
Copy CodeThe code is as follows: <td align= "left" width= "><input type=" checkbox "Name=" Code_value "value=" <%= Userdeffieldvaluebean.getudfvalue ()%> "></td>
Compare full JS checkbox Select All, deselect all, delete function code
