在Span中查找文本并在警报中显示(Finding text within a Span and displaying in an alert)

在Span中查找文本并在警报中显示(Finding text within a Span and displaying in an alert)

在我当前的页面上，我目前有一个在iframe中呈现的范围：

<span id="SpanID_ctrlHelp_lblHelp">HelpText</span>

使用以下代码，我可以在警报中显示“HelpText”：

$('div[id*="MyControl"]').find("[id*='_fraDefaultFrame']") .contents() .each(function () { var txtBox = $('#SpanID_ctrlHelp_lblHelp').html(); alert(txtBox); });

上面的代码运行良好，但我想为给定屏幕上的每个帮助文本实例激活一个警报。 请注意，所有可用的帮助文本都有一个span ID，其中包含以下“_ctrlHelp_lblHelp”

希望有人能理解这一点并协助......

On my current page I currently have a span which is rendered within an iframe:

<span id="SpanID_ctrlHelp_lblHelp">HelpText</span>

With the below code I am able to display 'HelpText' within an alert:

$('div[id*="MyControl"]').find("[id*='_fraDefaultFrame']") .contents() .each(function () { var txtBox = $('#SpanID_ctrlHelp_lblHelp').html(); alert(txtBox); });

The above code works well however I would like to activate an alert for every instance of help text on a given screen. Note all available help text has a span ID which contains the following "_ctrlHelp_lblHelp"

Hope someone can make sense of this and assist...

这样做：

var txtBox = $('[id$="_ctrlHelp_lblHelp"]').html(); // id ends by

或这个：

var txtBox = $('[id*="_ctrlHelp_lblHelp"]').html(); // id contains

---

或者你可以试试这个：

$('[id$="_ctrlHelp_lblHelp"]').each(function(){ alert(this.innerHTML); });

This would do:

var txtBox = $('[id$="_ctrlHelp_lblHelp"]').html(); // id ends by

or this:

var txtBox = $('[id*="_ctrlHelp_lblHelp"]').html(); // id contains

---

Or you may try this:

$('[id$="_ctrlHelp_lblHelp"]').each(function(){ alert(this.innerHTML); });
