輸入字段文本不變

Question

我想改變輸入字段文本，使用javascript onblur和onfocus，但保存後。我沒有看到任何改變。以下是代碼

<input type="text" name="EMAIL" class="required email" value="<?php _e('email','woothemes'); ?>" id="mce-EMAIL" onfocus="if (this.value == '<?php _e('email','woothemes'); ?>') {this.value = '';}" onblur="if (this.value == '') {this.value = '<?php _e('email','woothemes'); ?>';}"> 

到

<input type="text" name="EMAIL" class="required email" value="<?php _e('your@email.com','woothemes'); ?>" id="mce-EMAIL" onfocus="if (this.value == '<?php _e('your@email.com','woothemes'); ?>') {this.value = '';}" onblur="if (this.value == '') {this.value = '<?php _e('your@email.com','woothemes'); ?>';}"> 

的術語<?php _e(); ?>用於翻譯WordPress的，我改成了迴音，即使這樣，我看不出有什麼變化。
我錯過了什麼？

Answer 1

onfocus="if (this.value == '<?php _e('your@email.com','woothemes'); ?>') {this.value = '';}" onblur="if (this.value == '') {this.value = '<?php _e('your@email.com','woothemes'); ?>';}"> 
          ^_________^    ^__^  ^_____^ 

注意代碼段單引號的範圍試試這個，

onfocus="if (this.value == '<?php _e(\"your@email.com\",\"woothemes\"); ?>') {this.value = '';}" onblur="if (this.value == '') {this.value = '<?php _e(\"your@email.com\",\"woothemes\"); ?>';}">
