僅當選中複選框時,才需要更改文本輸入的值。兩個輸入(文字和複選框)具有相同的類:JQUERY:從選中複選框的文本輸入更改值
<label for="text_to_apply">Write your text: </label>
<input type="text" id="text_to_apply" name="text_to_apply" value="">
<button type="button" id="btn_apply">Change</button>
<form id="theform">
<input type="text" value="1" id="one1" class="one"><input type="checkbox" id="one1_" class="one"><br>
<input type="text" value="1" id="one2" class="one"><input type="checkbox" id="one2_" class="one"><br>
<input type="text" value="1" id="one3" class="one"><input type="checkbox" id="one3_" class="one"><br>
<input type="text" value="1" id="one4" class="one"><input type="checkbox" id="one4_" class="one"><br>
<input type="text" value="2" id="two1" class="two"><input type="checkbox" id="two1_" class="two"><br>
</form>
</div>
<script>
$('#btn_apply').click(function() {
var mytext = $('#text_to_apply').val();
if ($('#theform').find('.one input:checked')) {
$('#theform').find('.one:text').attr('value', mytext);
}
});
</script>
</body>
我運行的想法。請幫忙!
謝謝!
