Implementation code for setting page text box based on jquery that can only input numbers_jquery

The code is as follows:

Copy code The code is as follows:

$("#money").bind ("propertychange",function() {
if(""!=this.value){
var str = this.value.replace(/(^s*)|(s*$)/g, "");
if(this.value != str )
this.value = str;
}
if( isNaN(Number(this.value)))
this.value = this.value.replace(/[D]/,'');
});

JQuery is used here to bind to the onpropertychange event of the text box with the id of money.
The code below even blocks the decimal point

Copy the code The code is as follows:

$("#phone").bind("propertychange", function() {
if(""!=this.value){
var str = this.value.replace(/(^s*) |(s*$)/g, "");
if(this.value != str )
this.value = str;
}
if (this.value.indexOf(' .') != -1) {
this.value = this.value.replace(/[.]/, '');
this.focus(); }
if (isNaN(Number (this.value))) {
this.value = ($.trim(this.value)).replace(/[D]/, '');
this.focus(); } }) ;

Finally, it is best to block the input method. This can be achieved through css, ime-mode:disabled.
If it is very strict, you can add a prohibition on pasting and dragging.
How to prohibit pasting and dragging

ondragenter:expression(ondragenter=function(){return false;});
onpaste:expression(onpaste=function(){return false;});
}

If you still need to disable the function of inputting Chinese, you only need to add one more sentence.
