I have an html table built from a database query which loops through and creates a button for each camera name found and puts them in a table:
<?php
for($i=0;$i<$num_rows;$i++)
{
?>
<tr>
<td>
<input type="submit" class="play" data-hash="<?php echo $result_cameras[$i]["camera_hash"]; ?>" value="<?php echo $result_cameras[$i]["camera_name"]; ?>">
</td>
</tr>
<?php
}
?>
This resolves to something like this:
<tr>
<td>
<input type="submit" class="play" data-hash="0d3d0ac6e54a640c73f1149d4d0bbc38e99d10f5" value="Office Window">
</td>
</tr>
<tr>
<td>
<input type="submit" class="play" data-hash="b824cba374c3d5ab7806ad8260c939323c03147b" value="aaa">
</td>
</tr>
<tr>
<td>
<input type="submit" class="play" data-hash="ec9658f0c1855e2e2ac09ae284f5e6990dbf445d" value="laptop">
</td>
</tr>
Notice the data hash attribute is different for each button. I want to process this button with my jquery code:
$(".play").click(function(){
var camerahash = $('input').data('hash');
console.log($('input').data('hash'));
});
No matter which button I click I will always get the hash from the first button I click: 0d3d0ac6e54a640c73f1149d4d0bbc38e99d10f5
. Any help is appreciated.
$('input').data('hash')
为您提供选择中第一个输入的data属性,使用$(this).data('hash')
获得当前单击的输入的data属性
You need to specify which input element to read. Try something like:
$(".play").click(function(){
$this = $(this);
var camerahash = $this.data('hash');
console.log($this.data('hash'));
});
You are always calling the first object of .play. This would be a correct way:
$('.play').on('click', function(){
var camerahash = $(this).data('hash');
});
You could always grab them by using the .attr(data-hash)
html5 attribute.
Try:
$('.play').on('click', function() {
var _hash = $(this).attr('data-hash');
console.log(_hash);
});
Your selector will return the first one that it comes to. Use this instead
<script>
$("input.play").click(function() {
alert($(this).data('hash'));
});
</script>
