我有一個angucomplete-ALT輸入字段,而我期望的功能是改變佔位符爲藍色,當有人專注於IT的顏色..如何將顏色添加到angucomplete-ALT的佔位符
<div tpcomplete-alt='true' input-class='isused form-control' match-class='autocomplete-highlight' name='name' minlength='3' placeholder='Skill Name, E.g. Java' selected-object="onSelectSkill" title-field="text" remote-url='/api/skills?q=' override-suggestions="true" style='width:150px;'></div>
向'input-class'添加一個類只會改變我輸入的文本的顏色,但是我想改變佔位符的顏色。誰能告訴我做正確的方式.. 感謝
