< input type =   text name =   useremail value =  电子邮件... size =   20 
 onfocus =   this.style.background ='＃0b385f' $ b $bönblur=   this.style.background ='＃1a527d' /> 
 
< input type =   text name =   useremail value =  电子邮件... size =   20 
 onfocus =   this.style.background ='＃0b385f' $ b $bönblur=   this.style.background ='＃1a527d' /> 

i想要从文本框移动焦点时将这些文本框文本设为粗体。

解决方案

当你想改变css属性时你不能使用破折号（ - ）使用cammel案例：



this.style.font-weight - > this.style.fontWeight 的

when you want to change css properties you cannot use dash(-) use cammel case:

this.style.font-weight -> this.style.fontWeight
