JQuery restricts that only numbers and decimal places can be entered in the text box.

This article mainly introduces JQuery's method of limiting the number and decimal point of a text box.

 

The Code is as follows:

$ (Function (){

/* JQuery restricts that only numbers can be entered in the text box */

$ (". NumText"). keyup (function (){

$ (This). val ($ (this). val (). replace (/D | ^ 0/g ,''));

}). Bind ("paste", function () {// CTR + V event processing

$ (This). val ($ (this). val (). replace (/D | ^ 0/g ,''));

}).Css ("ime-mode", "disabled"); // the CSS setting input method is unavailable.

 

/* JQuery limits that only numbers and decimal places can be entered in the text box */

$ (". NumDecText"). keyup (function (){

$ (This). val ($ (this). val (). replace (/[^ 0-9.]/g ,''));

}). Bind ("paste", function () {// CTR + V event processing

$ (This). val ($ (this). val (). replace (/[^ 0-9.]/g ,''));

}).Css ("ime-mode", "disabled"); // the CSS setting input method is unavailable.

});

 

 

Add the class name to the text box to be verified, as shown in the following code:

 

The Code is as follows:

<Input type = "text" class = "txt NumText" Width = "100px" runat = "server"/>
