我需要一些帮助:我有以下表格:
<form id="myForm" method="post" action="?action=agc">
<input type="hidden" name="start_date" value="<?= $_POST['start_date'] ?>" />
<input type="hidden" name="end_date" value="<?= $_POST['end_date'] ?>" />
<input type="hidden" name="c_name" value="<?= $_POST['c_name'] ?>" />
<input type="hidden" name="cluster" value='<?= $abn_cluster[0] ?>' />
<input type="hidden" name="abn" value="abn" />
<a href="javascript:addOption();">Add percent</a> <br /><br />
ABN percent<br />
<input type="text" name="poll[option][0][percent]" class="toAdd"> <input type="text" name="poll[option][0][name]" value="<?= $_POST['c_name'] ?>_0_"> <input type="checkbox" class="optionBox" value="True" name="poll[option][0][control_sample]" /><br />
<script>
var optionNumber = 1;
function addOption() {
var theForm = document.getElementById("myForm");
var newOption = document.createElement("input");
var newOption2 = document.createElement("input");
var newOption3 = document.createElement("input");
var newLabel = document.createElement("label");
var newContent = document.createTextNode(" ");
var newContent2 = document.createTextNode(" ");
newOption.name = "poll[option]["+optionNumber+"][percent]";
newOption.type = "text";
theForm.appendChild(newOption);
theForm.appendChild(newContent);
newOption2.name = "poll[option]["+optionNumber+"][name]";
newOption2.type = "text";
newOption2.value = "<?= $_POST['c_name'] ?>_"+optionNumber+"_"
theForm.appendChild(newOption2);
theForm.appendChild(newContent2);
newOption3.name = "poll[option]["+optionNumber+"][control_sample]";
newOption3.type = "checkbox";
newOption3.className = "optionBox";
newOption3.value = "True"
theForm.appendChild(newOption3);
theForm.appendChild(document.createElement("br"));
optionNumber++;
}
</script>
</p>
</div>
<div class="modal-footer" id="appendform">
<button type="submit" class="btn btn-primary">Continue</button>
</form>
现在因为某些输入是根据请求生成的,所以我不知道如何检查 (.toAdd) 的总和。而且我基本上需要在提交之前确保它等于100。什么是我的问题的解决方案?谢谢。
