Js removes all spaces and disallow spaces when entering values in the input box.

/*** Whether to remove all spaces * @ param str * @ param is_global if it is g or G, remove all * @ returns */function Trim (str, is_global) {var result; result = str. replace (/(^ \ s +) | (\ s + $)/g, ""); if (is_global.toLowerCase () = "g") {result = result. replace (/\ s/g, "");} return result ;}

/*** Remove space input * @ param e * @ returns {Boolean} */function inputSapceTrim (e, this_temp) {this_temp.value = Trim (this_temp.value, "g "); var keynum; if (window. event) // IE {keynum = e. keyCode} else if (e. which) // Netscape/Firefox/Opera {keynum = e. which} if (keynum = 32) {return false;} return true ;}

/*** Do not enter Spaces * @ param e * @ returns {Boolean} */function banInputSapce (e) {var keynum; if (window. event) // IE {keynum = e. keyCode} else if (e. which) // Netscape/Firefox/Opera {keynum = e. which} if (keynum = 32) {return false;} return true ;}
