如何使用javascript在输入文本中插入符号

Question

I need some help in inserting html symbols like checkmark character using javascript. Here is my code.

<script>
function me(){
var a = document.getElementById("me").value = 3;
if(a==3){
document.getElementById("u").value = "checkmark symbol here";
}
</script>
<input type="text" id="me" value=""/>
<input type="text" id="u" value="It will display here a checkmark symbol any symbo"/>
<input type="button" value="click" onclick="me()" />

Any help will be appreciated. Thanks!

Answer 1

The JS string "\✓" should produce a checkmark (✓). In general, you can find the character you want on this site then copy the "C/C++/Java source code" section: Unicode Character 'CHECK MARK' (U+2713) .

Answer 2

试着改变这个

if (parseInt(document.getElementById("me").value)==3)
