Идентификаторы должны быть уникальными на странице. И про document.write. |
<script type="text/javascript">
window.onload = function(){ var count = 0; document.getElementById("check").onclick = function(){ document.getElementById("input").value = (this.checked) ? count+=150 : count-=150; }; }; </script> <input type="checkbox" id="check" value="" /> <input type="checkbox" id="check" value="" /> <input type="checkbox" id="check" value="" /> <input type="text" id="input" value="0" /> |
Цитата:
<script type="text/javascript">
window.onload = function(){
var count = 0;
document.getElementById("check0").onclick = function(){
document.getElementById("input").value = (this.checked) ? count+=150 : count-=150;
};
document.getElementById("check1").onclick = function(){
document.getElementById("input").value = (this.checked) ? count+=150 : count-=150;
};
document.getElementById("check2").onclick = function(){
document.getElementById("input").value = (this.checked) ? count+=150 : count-=150;
};
};
</script>
<input type="checkbox" id="check0" value="" />
<input type="checkbox" id="check1" value="" />
<input type="checkbox" id="check2" value="" />
<input type="text" id="input" value="0" />
