问题是,我无法弄清楚,当值文本输入字段中的任何一个变为红色时,如何显示“拒绝批处理按钮” 。
<div class="text-center">
<button type="submit" class="btn btn-success btn-sm nodisp" data-toggle="tooltip" id="acceptbtn">send to finish stock</button>
<button type="submit" class="btn btn-danger btn-sm nodisp" data-toggle="tooltip" id="rejectbtn">reject the batch</button>
</div>
<?php
$pro_item_id = $_GET['proitem'];
include_once('../backend/ProductQCAttribute.php');
$pro_qc_attr = new ProductQCAttribute();
$all_qc_attr = $pro_qc_attr->get_all_qc_attributes_by_product_item_id($pro_item_id);
$row = 0;
foreach ($all_qc_attr as $single_qc_attrb) {
echo ("<tr>" .
"<td>" . "<input type='hidden' name='qc_attrb_id[]' id='qc_attrib_id_$row' class='form-control' value='$single_qc_attrb->pro_qc_attr_id' >". $single_qc_attrb->pro_qc_attr_name ."</td>" .
"<td>" . "<input type='text' name='qc_value[]' id='qc_value_$row' class='form-control check-range' onchange='checkValue($row,$single_qc_attrb->pro_qc_attr_low_margin,$single_qc_attrb->pro_qc_attr_high_margin)' >" ."</td>" .
"<td>" . "<input type='text' name='low_margin[]' id='low_margin_$row' class='form-control' value='$single_qc_attrb->pro_qc_attr_low_margin' readonly >" ."</td>" .
"<td>" . "<input type='text' name='high_margin[]' id='high_margin_$row' class='form-control' value='$single_qc_attrb->pro_qc_attr_high_margin' readonly >" ."</td>".
"</tr>");
$row++;
}
?>
// change the color of input fields based on input user provide
// function working correclty
function checkValue(row,lowMargin,highMargin) {
if($("#qc_value_"+row).val() >= lowMargin && $("#qc_value_"+row).val() <= highMargin) {
$("#qc_value_"+row).addClass('green-check');
$("#qc_value_"+row).removeClass('red-reject'); // red-reject class I defined in the css file..its ok
} else {
$("#qc_value_"+row).addClass('red-reject');
$("#qc_value_"+row).removeClass('green-check');
}
check_green(row); // calling to this might be in the wrong place, I tried different places but didn't work it out.
}
// check weather all input fields are green, then show the accept button
// function working correctly
function check_green(row) {
if($("#qc_value_"+row).hasClass('green-check')) { // green-check class I defined in the css file..its ok
$("#status").val('pass');
$("#acceptbtn").removeClass('nodisp'); // nodisp class I defined in the css file..its ok
$("#rejectbtn").addClass('nodisp');
} else {
$("#status").val('fail');
$("#rejectbtn").removeClass('nodisp');
$("#acceptbtn").addClass('nodisp');
}
}
我尝试过并且无法弄清楚我在这里做错了什么或代码中缺少什么..如果有人可以让我深入了解如何解决这个问题,将不胜感激。

您可以检查表单中的任何控件是否具有red-reject
类,并相应显示按钮。
jQuery
集合具有一个length
属性供您使用。
我对标记进行了一些更改,以使用事件侦听器代替onChange
,它将标记与逻辑分离,从而更易于维护。
// Execute whenever a user input changes
$('.check-range').on('change', function() {
// Cache the jquery object
$this = $(this);
currentValue = parseFloat($this.val());
// Find corresponding range values
lowMargin = parseFloat($this.closest('tr').find('[id^="low_margin"]').val());
highMargin = parseFloat($this.closest('tr').find('[id^="high_margin"]').val());
// Check bounds and add classes
if ((currentValue >= lowMargin) && (currentValue <= highMargin)) {
$this.addClass('green-check');
$this.removeClass('red-reject');
} else {
$this.addClass('red-reject');
$this.removeClass('green-check');
}
// Update button status
// 0 is falsey, any other value is truthy
if ($('.check-range.red-reject').length) {
// There are invalid parameters
$("#rejectbtn").removeClass('nodisp');
$("#acceptbtn").addClass('nodisp');
} else {
$("#acceptbtn").removeClass('nodisp');
$("#rejectbtn").addClass('nodisp');
}
})
.green-check {
background-color: green;
}
.red-reject {
background-color: red;
}
.nodisp {
display: none;
}
