Get multiple checkbox values and multiple checkbox values
var objs = document.getElementsByTagName("input"); for (var i = 0; i < objs.length; i++) { if (objs[i].type.toLowerCase() == "checkbox" && objs[i].checked) alert(objs[i].value); }
In js, how does one obtain multiple values selected in the checkbox?
Doucument. getElement (id). value
How can I obtain the selected value of the check box from js?
<Input type = "checkbox" id = "box" value = "sss1"/>
<Input type = "checkbox" id = "box" value = "sss2"/>
<Input type = "checkbox" id = "box" value = "sss2"/>
<Input type = "checkbox" id = "box" value = "sss2"/>
<Input type = "checkbox" id = "box" value = "sss2"/>
<Input type = "button" name = "btnOK" value = "OK"/>
<Script for = btnOK event = onclick>
Var value = "";
For (var I = 0; I <box. length; I ++ ){
If (box [I]. checked) {// determine whether the check box is selected
Value = value + box [I]. value + ""; // piece together the values... depending on your needs,
}
}
Alert (value); // output the values of the check boxes you selected
</Script>
