//禁止输入空格

var InputName;

function getInputName(N){

InputName = document.getElementById(N).name;

}

function checkSpace(event){

if(InputName != "laddr"){

var keynum;

if(window.event){//IE

keynum = event.keyCode;

}else if(event.which){

keynum = event.which;

}

if(keynum == 32){

return false;

}

return true;

}else {

return true;

}

}

document.onkeydown = checkSpace;
