Get value onblur from input fields in a loop
提问by LITguy
Below is how I made an alert showing the "dynamic" id using onblur. I have a while loop with input fields so the id is pulling from a unique id in a database.
下面是我如何使用 onblur 显示“动态”ID 的警报。我有一个带有输入字段的 while 循环，因此 id 是从数据库中的唯一 id 中提取的。
How would I get the value too? Normally I would just set a variable like usual but it's in a loop so I'm not understanding how.
我将如何获得价值？通常我会像往常一样设置一个变量，但它处于循环中，所以我不明白如何。
<script type="text/javascript">
function doUpdateEntries(clicked_id) {
alert(clicked_id);
// how do I get the value AND id?
}
</script>
while ($row = mysql_fetch_assoc($result)) {
<input onblur="doUpdateEntries(this.id);" id=".$row['entry_id']." name=".$row['entry_id']." type="text" value=".$row['reviews'].">
}

You could simply pass through the value to the function doUpdateEntriesas another parameter.
您可以简单地将值doUpdateEntries作为另一个参数传递给函数。
<script type="text/javascript">
function doUpdateEntries(id, value) {
alert(id);
alert(value);
}
</script>
while ($row = mysql_fetch_assoc($result)) {
<input onblur="doUpdateEntries(this.id, this.value);" id=".$row['entry_id']." name=".$row['entry_id']." type="text" value=".$row['reviews'].">
}

As Ankit mentions… just pass in this, à la
正如 Ankit 提到的……只是传入this，à la
<input onblur="doUpdateEntries(this);" id=".$row['entry_id']." name=".$row['entry_id']." type="text" value=".$row['reviews'].">

function doUpdateEntries(_this) {
var _id = _this.id;
var _name = _this.value;
}
