Question

当我试图检查引导单选按钮时，我正在比较2个变量。我完全100％确定相等，但按钮未标记为已选中。这可能是什么问题？

echo '<label class="btn btn-secondary"><input type="radio" id="bedrijf" name="bedrijf" value="'.$value.'" '; 
if($row_list['bedrijf'] == $value) { 
    echo 'checked '; 
}
echo 'autocomplete="off" onclick="validate_add()" onmousemove="validate_add()"><img src="images/logo_'.$value.'_small.png" height="30"></label>';

HTML输出

<div class="form-group btn-group" data-toggle="buttons"><label class="btn btn-secondary"><input type="radio" id="bedrijf" name="bedrijf" value="mb" autocomplete="off" onclick="validate_add()" onmousemove="validate_add()"><img src="images/logo_mb_small.png" height="30"></label><label class="btn btn-secondary"><input type="radio" id="bedrijf" name="bedrijf" value="thure" checked autocomplete="off" onclick="validate_add()" onmousemove="validate_add()"><img src="images/logo_thure_small.png" height="30"></label><label class="btn btn-secondary"><input type="radio" id="bedrijf" name="bedrijf" value="torza" autocomplete="off" onclick="validate_add()" onmousemove="validate_add()"><img src="images/logo_torza_small.png" height="30"></label></div>

Answer 1

autocomplete关键字前面需要一个空格。目前，它呈现为... checkedautocomplete="off" onclick="...。

您还可以按如下方式内联if语句：

echo '<label class="btn btn-secondary">
    <input type="radio" id="bedrijf" name="bedrijf" value="'.$value.'" '.($row_list['bedrijf'] == $value ? 'checked' : '').' autocomplete="off" onclick="validate_add()" onmousemove="validate_add()">

    <img src="images/logo_'.$value.'_small.png" height="30">
</label>';

选中Bootstrap按钮标记回显
