Passing string with space character as parameter to on-click function generated by javascript
提问by Lasang
My hypertlink generated by JavaScript is as follows:
我的JavaScript生成的超链接如下：
'<a href="#" onClick=passSearchTerm("' +aa + '");>View</a>'
'<a href="#" onClick=passSearchTerm("' +aa + '");>View</a>'
The parameter passes wells when the string is as follows:
字符串如下时参数pass wells：
var aa = 'TAGS(\"ab\")';
var aa = 'TAGS(\"ab\")';
I confirmed it by alerting inside the function
我通过在函数内部发出警报来确认它
function passSearchTerm(aa) { alert(aa); }
功能 passSearchTerm(aa) { 警报(aa); }
However, this wont alert when the var is defined as follows:
但是，当 var 定义如下时，这不会发出警报：
var aa = 'TAGS(\"a b\")'; //space between "a" and "b"
var aa = 'TAGS(\"ab\")'; //“a”和“b”之间的空格
Can anyone suggest me how to pass such string? Thanks in advance for your help. Actually I am trying to pass likely following string:
谁能建议我如何传递这样的字符串？在此先感谢您的帮助。实际上，我正在尝试传递可能的以下字符串：
TAGS("a or b")
标签（“a 或 b”）

While generating ur hyperlink by javascript use encodeURIComponent ex.
通过 javascript 生成您的超链接时，请使用 encodeURIComponent ex。
"<a href=\"#\" onclick=\"passSearchTerm('" + encodeURIComponent(aa) + "')\">View</a>"
and while retriving use decodeURIComponent
并在检索时使用 decodeURIComponent
function passSearchTerm(aa) { alert(decodeURIComponent(aa)); }

I think you've just overused your escapes.
我认为你只是过度使用了你的逃避。
This works for me.
这对我有用。
var aa = 'TAGS("a b")';
// var aa = 'TAGS(\"a b\")';
var e = document.createElement("A");
e.href = "#";
e.setAttribute( "onClick", "passSearchTerm('" + aa + "');" );
e.innerText = "View";
document.body.appendChild(e);
function passSearchTerm(p){
alert(p);
}
</script>

var aa = 'TAGS(\"a b\")';
