jquery sets the input value to white

In web development, we often need to dynamically modify the content of the page through JavaScript or jQuery. If you need to set the value of a text input box to white, you can use the following jQuery code to achieve it:

$('input[type="text"]').css('color', 'white');

In the above code, we first select all input boxes of type text, and then use css() Method sets their text color to white. In actual development, if we only need to select one input box on the page, we can use the ID or class of the input box to locate it.

$('#myInput').css('color', 'white');

In the above code, we use the ID selector #myInput to select the specified input box, and then call the css() method to set its text color.

It should be noted that if you set the font color of the input element in HTML and the style attribute has a higher priority, the above code may not take effect. If you want to force the text color of the input box to white, you can use the !important keyword.

$('#myInput').css('color', 'white !important');

In the above code, we added the !important keyword after setting the color value, indicating that this is a mandatory style and will override other style attributes.

In addition to using CSS styles to set the text color, we can also use the attr() method to modify the value attribute of the input element to change the color of the text in the input box. The following is a sample code:

$('#myInput').val('白色文字').attr('style', 'color: white !important');

In the above code, we first use the val() method to set the text value of the input box, then use the attr() method to add a style attribute to the element, and change the color The property is set to white.

In general, we can use a variety of methods to set the text color of an input box to white, but we need to choose the most appropriate method according to the actual situation and pay attention to the impact of priority.
