//注意: 操作checkbox的checked,disabled属性时jquery1.6以前版本用attr,1.6以上(包含)建议用prop
//1、根据id获取checkbox
$(
"#cbCheckbox1"
);
//2、获取所有的checkbox
$(
"input[type='checkbox']"
);
//or
$(
"input[name='cb']"
);
//3、获取所有选中的checkbox
$(
"input:checkbox:checked"
);
//or
$(
"input:[type='checkbox']:checked"
);
//or
$(
"input[type='checkbox']:checked"
);
//or
$(
"input:[name='ck']:checked"
);
//4、获取checkbox值
//用.val()即可,比如:
$(
"#cbCheckbox1"
).val();
//5、获取多个选中的checkbox值
var
vals = [];
$(
'input:checkbox:checked'
).each(
function
(index, item) {
vals.push($(
this
).val());
});
//6、判断checkbox是否选中(jquery 1.6以前版本 用 $(this).attr("checked"))
$(
"#cbCheckbox1"
).click(
function
() {
if
($(
this
).prop(
"checked"
)) {
alert(
"选中"
);
}
else
{
alert(
"没有选中"
);
}
});
//7、设置checkbox为选中状态
$(
'input:checkbox'
).attr(
"checked"
,
'checked'
);
//or
$(
'input:checkbox'
).attr(
"checked"
,
true
);
//8、设置checkbox为不选中状态
$(
'input:checkbox'
).attr(
"checked"
,
''
);
//or
$(
'input:checkbox'
).attr(
"checked"
,
false
);
//9、设置checkbox为禁用状态(jquery<1.6用attr,jquery>=1.6建议用prop)
$(
"input[type='checkbox']"
).attr(
"disabled"
,
"disabled"
);
//or
$(
"input[type='checkbox']"
).attr(
"disabled"
,
true
);
//or
$(
"input[type='checkbox']"
).prop(
"disabled"
,
true
);
//or
$(
"input[type='checkbox']"
).prop(
"disabled"
,
"disabled"
);
//10、设置checkbox为启用状态(jquery<1.6用attr,jquery>=1.6建议用prop)
$(
"input[type='checkbox']"
).removeAttr(
"disabled"
);
//or
$(
"input[type='checkbox']"
).attr(
"disabled"
,
false
);
//or
$(
"input[type='checkbox']"
).prop(
"disabled"
,
""
);
//or
$(
"input[type='checkbox']"
).prop(
"disabled"
,
false
);
