原来input 里写 value="Enter search keywords here" onfocus="if (this.value == 'Enter search keywords here') this.value = '';" onblur="if (this.value == '') this.value = 'Enter search keywords here';"不知道在TextBox 里怎么赋值写呢?
调试欢乐多
this.TextBox1.attribuates.add("onfocus","if (this.value == 'Enter search keywords here') this.value = '';");

后台写JS
