问题描述
我正在编写一些使用用PHP呈现的字符串的JavaScript代码。我如何在PHP字符串中避免单引号(只有单引号)? < script type =text / javascript >
$('#myElement')。html('say hello to<?php echo $ mystringWithSingleQuotes?>');
< / script>
解决方案
很简单: echo str_replace ('\'','\\\\'',$ myString);
但是,我建议使用和功能会更可靠(例如引用新行):
<?php $ data = array('myString'=>'...'); ?>
< script>
var phpData =<?php echo json_encode($ data)?> ;;
alert(phpData.myString);
< / script>
I am writing some javascript code that uses a string rendered with PHP. How can I escape single quotes (and only single quotes) in my PHP string?
<script type="text/javascript">
$('#myElement').html('say hello to <?php echo $mystringWithSingleQuotes ?>');
</script>
解决方案
Quite simply: echo str_replace('\'', '\\\'', $myString);
However, I'd suggest use of JSON and json_encode()
function as it will be more reliable (quotes new lines for instance):
<?php $data = array('myString' => '...'); ?>
<script>
var phpData = <?php echo json_encode($data) ?>;
alert(phpData.myString);
</script>
