我希望不要在密码部分输入空格. [英] I want spaces not to be entered in password section.

问题描述

请帮帮我，因为我是jquery的新手，所以我不知道如何添加和实现正则表达式.

除了空间，任何东西都可以迷惑.

我尝试过的事情:

Help me out, as i am new to jquery, i dono how add and implement the regular expression.

except space anything can be enetered.

What I have tried:

$("#clientPassWord").on("change", function () {
    var clientPassWord=$("#clientPassWord").val().length;
    var clientPassWord1=$("#clientPassWord").val();
    if(clientPassWord==null || clientPassWord<=0){
    $("#passmsg").show();
    $("#passmsg").html("This is a required field. You can’t leave it empty.");
    }   
    else{
    if(clientPassWord>=8 ) {
    $("#passmsg").hide();
    $("#joinbtn").removeAttr('disabled'); 
    if (clientPassWord1.toLowerCase().match("paperindex") || clientPassWord1.toUpperCase().match("PAPERINDEX") || clientPassWord1.toLowerCase().match("paperindexcom") || clientPassWord1.toUpperCase().match("PAPERINDEXCOM") ) {                    
    $("#passmsg").show();
    $("#passmsg").html(""PaperIndex" and variations of this word are not allowed here");
    }  
    else{
                $("#passmsg").hide();
             $("#joinbtn").removeAttr('disabled');
             }                           

    }
    else {
        $("#passmsg").show();
    $("#passmsg").html("Short passwords are easy to guess. Enter at least 8 characters.");
    $("#joinbtn").attr('disabled', 'disabled');
    
        }

        }        
    });

推荐答案

(" ).on( change"， var clientPassWord =

("#clientPassWord").on("change", function () { var clientPassWord=

(" ).val().length; var clientPassWord1 =

("#clientPassWord").val().length; var clientPassWord1=

(" ).val(); 如果(clientPassWord == 空 || clientPassWord< = 0 ){

("#clientPassWord").val(); if(clientPassWord==null || clientPassWord<=0){
