JS realizes that the text box cannot be edited
Method 1: onfocus=this.blur() When the mouse cannot be placed, leave the focus
<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="Chinese" disabled >
<input type="text" name="input1" value="Chinese" disabled="true">
Disabled input elements defined with disabled="disabled" are neither usable nor clickable.
readonly="readonly" Read-only fields cannot be modified.
js dynamically implements the uneditable state of the text box
Two methods:
$("#id").attr("readOnly",false); not editable, you can pass values
$("#id").attr("disabled",false); cannot be edited and cannot be passed by value
Note that the O in readOnly is capitalized
