Use jQuery trim to remove leading and trailing white space
使用 jQuery 修剪去除前导和尾随空格
$.trim(" test case "); // 'test case'
To remove all whitespace...
要删除所有空格...
" test ing ".replace(/\s+/g, ''); // 'testing'
To remove whitespace as it is entered...
要在输入时删除空格...
$(function(){
$('#noSpacesField').bind('input', function(){
$(this).val(function(_, v){
return v.replace(/\s+/g, '');
});
});
});

$('#noSpacesField').keyup(function() {
$(this).val($(this).val().replace(/ +?/g, ''));
});
This will remove spaces as you type, and will also remove the tab char.
这将在您键入时删除空格,并且还将删除制表符。

If you only wanna put numbers, try this! :D
如果你只想输入数字,试试这个!:D
$("#id").keyUp(function(){
if(isNaN($(this).val())) {
$(this).val(0);
}
$(this).val($(this).val().replace(/ +?/g, ''));
})
