[英]pass a string with double and single quotes as parameter to javascript function
Can anyone help me why this value from the database wont pass as a parameter 谁能帮我为什么数据库中的这个值不会作为参数传递
The value from the database has single and double quotes which i escaped using mysql_escape_string() before adding to the database. 来自数据库的值具有单引号和双引号,在添加到数据库之前,我使用mysql_escape_string()对其进行了转义。
<?php
$sample = "This is a test's \"output\".";
?>
<button onclick='myFunction(<?php echo addslashes($sample);?>)'></button>
<script>
function myFunction(val){
alert(val);
}
</script>
Thanks guys! 多谢你们!
json_encode($s, JSON_HEX_TAG+JSON_HEX_APOS+JSON_HEX_QUOT)
Use like this way. 像这样使用。 Hope it will work.
希望它能工作。
<?php
$sample = "This is a test's \"output\".";
$sample = json_encode($sample);
?>
<button onclick="myFunction(<?php echo htmlentities($sample); ?>)">Button</button>
<script>
function myFunction(val){
alert(val);
}
</script>
Use base64 encode. 使用base64编码。 You encode it in php, it wont have any quotes, and you can decode it in javascript, ie
您使用php对其进行编码,它不会包含任何引号,并且您可以使用javascript对其进行解码,即
<?php
$sample = "This is a test's \"output\".";
echo base64_encode($sample);// VGhpcyBpcyBhIHRlc3QncyAib3V0cHV0Ii4=
?>
then 然后
console.log(atob("VGhpcyBpcyBhIHRlc3QncyAib3V0cHV0Ii4=")); // This is a test's "output".
so just: 所以就:
<button onclick="myFunction(atob(<?php echo base64_encode($sample); ?>))">Button</button>
