The default word color of textarea and the color of the word after the focus is obtained. After the focus is obtained, the default color disappears.

<Textarea cols = "50" rows = "5" id = "textarea" onfocus = "if (value = 'get element focal point') {value =''; document. getElementById ('textarea '). style. color = '# 000'} "onblur =" if (value = '') {value = 'element focus disappears'; document. getElementById ('textarea '). style. color = '# 000000'} "> enter the content you want to enter </textarea>

By default, the selected items in the select statement are in gray color and then black (implemented in js)

<script>var unSelected = "#999";var selected = "#333";$(function () {$("select").css("color", unSelected);$("option").css("color", selected);$("select").change(function () {var selItem = $(this).val();if (selItem == $(this).find('option:first').val()) {$(this).css("color", unSelected);} else {$(this).css("color", selected);}});})</script>

The input value has a default value and is gray. when clicked, the default value disappears and the input value turns black.

<Script type = "text/javascript"> $ (function () {// input $ (". form input [text] "). each (function () {$ (this ). setDefauleValue () ;}); // a single call $ ("# key "). setDefauleValue () ;}) // sets the default value $. fn. setDefauleValue = function () {var defauleValue = $ (this ). val (); values (this).val(defaulevalue}.css ("color", "# eee"); return this. each (function () {$ (this ). focus (function () {if ($ (this ). val () = defauleValue) {$ (this ). val ("" ).css ("color", "#000"); // the color of the input value }}). blur (function () {if ($ (this ). val () = "") {watermark (this(.val(defaulevalue0000.css ("color", "#999"); // The default color }});});} </script>
