javascript - 如何在编辑弹出窗口时在 php 中获取 ajax 响应

Question

我的要求是当我单击编辑按钮时，然后使用 ajax 显示包含所选所有值的弹出窗口

我已发送这样的回复:

$data = array('cdid' => $model->cdid, 'cid' => $model->cid, 'icdcode' => $model->icdcode, 'category' => $model->category);
echo json_encode($data);

我在警报框中也得到了这样的响应

{"cdid":2,"cid":6,"icdcode":"6","category":2}

但问题是如何使用此数据在弹出窗口中显示选定的复选框或文本框值、下拉列表值。

Answer 1

嗯，可能有两种情况，即

场景 1，弹出窗口的 file.php 中有一组值，

PHP:

/* If you have json in your popup's file.php
   You needs to convert the json into php array.
*/
$values_array = json_decode($json_string, true);

/* Initializing default values to the variables that will be used to make selections*/

$check_radio = $check_select = "";
if( is_array($values_array) ){
    // supposing, the category is for radio buttons
    $check_radio = $values_array['category'];
    // supposing, the icdcode is for select box
    $check_select = $values_array['icdcode'];
}

HTML:

<input type="radio" name="category" value="ICD-10" <?php echo ($check_radio=='ICD-10') ? " checked='checked'":'';?>> ICD-10<br>
<input type="radio" name="category" value="ICD-9" <?php echo ($check_radio=='ICD-9') ? " checked='checked'":'';?>> ICD-9<br>

<select id="icd-code" name="icd-code" multiple>
  <option value="1001" <?php echo ($check_select=='1001') ? " selected='selected'":'';?>>1001</option>
  <option value="1002" <?php echo ($check_select=='1002') ? " selected='selected'":'';?>>1002</option>
</select>

场景 2，弹出窗口的 file.php 中没有 php 值数组或 json 数组，而是 Javascript JSON 对象:

// Assuming that you have JSON data like this
// var data = {"cdid":2,"cid":6,"icdcode":"6","category":2};

// So, you will need to Parse Json like this:
// https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse
var parsedData = JSON.parse(data);

// Making Checked the Radio buttons by name `category` and value
$("input[name=category][value='"+parsedData.category+"']").prop("checked",true);

//Making select options selected by option value
$('#icd-code option[value=' + parsedData.icdcode + ']').attr('selected', true);

希望它能帮助您解决问题:)
