jQuery使用HTML代码输入文本字段

Question

I have an input type="text" field and I want to display the pound sign and then a value

Using

val NewPrice1 = '2.5';
jQuery('#price_product_field').val('£' + NewPrice1);

But it just displays £ inside the box instead of the actual pound sign.

Answer 1

HTML entities doesn't work as a value in inputs, they are only converted when used in the HTML, use the character directly:

var NewPrice1 = '2.5';
jQuery('#price_product_field').val('£' + NewPrice1);

试试：

var NewPrice1 = '2.5'; jQuery('#price_product_field').html('£' + NewPrice1);
