For example, to create a most common input initial value, I used to write it in the input value. But one day the developer said that this would not work, and the value would be seven to eight % ...... @ The rest can only be said. Therefore, I want to write the initial value separately, so I am dumb. I will use the tag to write the initial value and locate it on the input so that the click and input get focus will disappear.
Words that must be firmly remembered. If you don't know what it is, you can make it directly. You are the most stupid person in the world !! I'm still trembling with my typing hands, and I can't forgive myself for that tiny mistake. For a lazy, stupid person. Put the correct words in what you want.

Hide: function (classN, id2 ){
Var idBox = document. getElementById (id2 );
ClassN. style. display = 'none ';
IdBox. focus ();
}
}
2. Use the background image method to add a background image to the input file, so that the image disappears when the image is focal points are obtained.
3.html 5 has a new attribute, the placeholder attribute, which will appear in the input consciously and appear in gray. However, it disappears only when the input is input. But html5, You know, ie8 is not supported.
The above problem is that the browser will remember the previously entered records. When the login page is opened again, the account password appears consciously. Yes, of course it is a good thing. But, for the previously set span label Positioning method, there will be a duplicate.
