Clear all forms on page load
提问by Tural Ali
I want to clear all forms on page load. I tried to use this function on domready, but it doesn't help. I'm new to JavaScript. Is there anything wrong with this function?
我想在页面加载时清除所有表单。我尝试在 domready 上使用此功能，但没有帮助。我是 JavaScript 的新手。这个功能有什么问题吗？
$(':input', form)
.not(':button, :submit, :reset, :hidden')
.val('')
.removeAttr('checked')
.removeAttr('selected');

You can try using the plain javascript resetmethod on a form
您可以尝试reset在表单上使用纯 javascript方法
$('form').each(function() { this.reset() });
This should reset each form to its default state.
这应该将每个表单重置为其默认状态。
To re-enable all checkboxes, you can try:
要重新启用所有复选框，您可以尝试：
$(':checkbox').prop('disabled', false);

maybe this is what your asking? not sure why you would need it. the fields should be blank on page load anyways. you should change the values php side.
也许这就是你要问的？不知道你为什么需要它。无论如何，这些字段在页面加载时应该是空白的。您应该更改 php 端的值。
$('input[type=text]').val('');
$('input[type=radio]').checked=false;
$('input[type=checkbox]').checked=false;
or maybe even
或者甚至
$("input:not(':button, :submit, :reset, :hidden')").val('').checked=false;

I would give each control i wanted to clear a class name of say class="ClearOnStartup"and then my jQuery would be;
我会给每个控件我想要清除 say 的类名，class="ClearOnStartup"然后我的 jQuery 将是；
$(function(){
$(".ClearOnStartup").val("");
});
I'd have a different one for check boxes only because I like to seperate things like this into batches.
我有一个不同的复选框只是因为我喜欢把这样的东西分成批次。
try this for checkboxes
试试这个复选框
$('.ClearOnStartup').attr('checked', false);
There is probably a better way tho
可能有更好的方法
