代码如下：
<SCRIPT LANGUAGE="JavaScript"> <!-- Begin function ignoreSpaces(string) { var temp = ""; string = '' + string; splitstring = string.split(" "); for(i = 0; i < splitstring.length; i++) temp += splitstring[i]; return temp; } // End --> </script> <center> <pre> </pre><font size="2">随意录入几个中间带空格的字符试试</font>. </center> <center> <form> <input type=text size=25 onBlur="this.value=ignoreSpaces(this.value);"> <input type=button value="Ok"> </form> </center>
