text boxes such as form input are read-only and not editable in HTML
Sometimes, we want the text box in the form to be read-only, so that the user cannot modify the information in it, such as the contents of input text, China Two words can not be modified sometimes, we want the text box in the form to be read-only, so that the user cannot modify the information in it, such as making <input type= " Text "Name=" input1 "value=" > "China" Two words can not be modified. The way to achieve is summed up, there are several.
Method 1:onfocus=this.blur () leave the focus when the mouse is not placed
<input type= "text" name= "INPUT1" value= "China" Onfocus=this.blur () >
Method 2:readonly
<input type= "text" name= "INPUT1" value= "China" readonly>
<input type= "text" name= "INPUT1" value= "China" readonly= "true" >
Method 3:disabled
<input type= "text" name= "INPUT1" value= "China" disabled= "true" >
A complete example:
<input name= "LY_QQ" type= "text" tabindex= "2" onmouseover= "This.classname= ' input_1 '" onmouseout= "this.className=" Input_2 ' "value=" 123456789 "disabled=" true "readonly=" true "/>
disabled= "true"The text is grayed out and cannot be edited.
readonly= "true"Text does not change color, it is also non-editable
CSS Masking input:<input style= "ime-mode:disabled" >
There are two ways to first: the disabled= "disabled" is defined so that the input element that is disabled is neither available nor clickable. Second: readonly= "readonly" read-only fields cannot be modified. However, the user can still use the TAB key to switch to the field, and can also select or copy its text.can take the value inside and use it.
