我为我的大学项目做了一个T恤设计网站。我添加了预览选项,当用户输入它时,它会显示在iframe中的t恤上。我还添加了一个继续按钮,当用户点击它时,我希望文本存储在数据库中但由于某种原因我不能让它工作。我正在使用ajax和php为数据库part.But javascript部分与ajax不工作。甚至警报功能不适用于onclick funtction ..
感谢任何帮助..
$(document).ready(function)() {
$("#btn").click( function() {
var tshirt-text =$('#tshirt-text').val();
var size =$('#size').val();
alert("tshirt-text");
$.ajax ({
type :'POST',
data :{tshirt-text:tshirt-text,size:size},
url :"storeinfo.inc.php",
success :function(result)
})
});
});
var $text = $( '.tshirt-text' );
var $demoText = $( '.demo-tshirt-text' );
$text.on( 'keyup', function ( e ) {
$demoText.text( $text.val() );
} );

答案 0 :(得分:2)
如果你检查控制台,你会发现问题是javascript click
函数内的第一行...
var tshirt-text = $('#tshirt-text').val();
...因为&#39; - &#39;不是javascript变量名的有效字符。只需按tshirttext
(在您的所有代码中)更改它,您就会看到alert
并且应该可以继续。
我希望它有所帮助
答案 1 :(得分:1)
你的JavaScript有些错误。尝试通过验证程序运行JavaScript(例如,http://beautifytools.com/javascript-validator.php)以查看错误的位置。除了发现的一个A. Iglesias之外,第1行还有一个额外的衣服括号,第9行重复第3行的tshirt-text
错误,以及在线成功的事件处理程序的语法13是不对的,但我不知道你要做什么。
你也有一个概念性的问题。第17行到第22行应位于$(document).ready
处理程序中。 ready
事件在初始HTML加载到浏览器并准备就绪后运行,因此对该事件处理程序的 之外的HTML元素的任何引用都可能在它们准备好之前引用它们
我想对你的问题发表评论,但这太长了,所以希望答案是可以的。也许一旦你修复了一些这些JavaScript问题,以编辑的形式发布你的问题的更新,然后我们可以看看如果它不起作用还会发生什么。
编辑:我重新格式化了您的JavaScript并尝试解决任何语法错误。如果您打开浏览器开发人员工具并运行此JS Fiddle(with comments和without comments),您将看到控制台中没有语法错误。这并不意味着它有效,只是它在语法上有效。实际上,这应该不起作用,因为我编写的AJAX success
处理程序只是记录响应。
$(document).ready ( // When function parameters and code blocks are big, I like to
// put the opening ( or { at the end of line and put the the
// closing } or ) in the same column way at the end. I find it
// is easier to keep track of openings and closings.
function() { // no extra close parenthesis right after "function"
$("#btn").click(
function()
{
var tshirtText = $('#tshirt-text').val(); // Variable names can only be
// letters, numbers, dollar symbols,
// and underscores. They cannot start
// with numbers.
var size = $('#size').val();
alert("tshirt-text");
$.ajax(
{ // For clarity, I'll separate out the opening ( and opening {
// and the closing } and closing ) when they are one after the other.
type: 'POST'
// I like to put my commas on the next line rather than the previous line.
// I think it makes it more clear that you're moving on to the next thing.
, data: { "tshirt-text": tshirtText, size: size } // You can specify names in
// this JSON-style syntax that
// aren't valid JavaScript
// identifiers, but you have
// to put them in quotes.

, success: function(data, textStatus, jqXhr)

}

var $text = $('.tshirt-text');
var $demoText = $('.demo-tshirt-text');
$text.on(

$demoText.text($text.val());
}
