复选框值是/否 [英] Checkbox value true/false
问题描述
我有一个带有复选框的表单,并且在提交带有错误的同一个视图时,我想在提交表单后保持选中状态.我听说value属性可以帮助我选中该复选框,因此我试图将其设置为true/false.无论如何,即使我单击输入值,它也保持"false".到底会发生什么? 我认为点击复选框后值会变为true/false
I have a form with checkbox and I want to keep it checked after submitting the form when it goes back to the same view with an error. I heard that the value attribute can help me to make the checkbox be checked so im trying to set it to true/false. Anyway, the input value stays "false" even if I click it. What happens exactly? I thought the value goes true/false after clicking the checkbox
<input type="checkbox" name="acceptRules" class="inline checkbox" id="checkbox1" value="false">
<script>
$("#checkbox1").is(':checked', function(){
$("#checkbox1").attr('value', 'true');
});
</script>
推荐答案
如果我理解这个问题,则希望根据是否选中该复选框来更改该复选框的值.
If I understand the question, you want to change the value of the checkbox depending if it is checked or not.
这是一种解决方案:
$('#checkbox-value').text($('#checkbox1').val());
$("#checkbox1").on('change', function() {
if ($(this).is(':checked')) {
$(this).attr('value', 'true');
} else {
$(this).attr('value', 'false');
}
$('#checkbox-value').text($('#checkbox1').val());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<input type="checkbox" name="acceptRules" class="inline checkbox" id="checkbox1" value="false">
<div id="checkbox-value"></div>
